i dont need it but im either going to make one or just buy one on amazon. not sure if you still need an authroized account or not, but either way, sounds like a cool gadget that has potentials. supposedly, if your xiaomi device fastboot mode is screwed up, you can use this cable with your laptop and itll connect you to a port so you can flash your stock rom or whatever. sounds like a super miracle cable if this **** works.

Hi folks,
i purchased a new usb cable today. its retractable, called 'Sync "N" Charge'. it is essentially the same connections as the stock usb connection cable.
the problem is when i try to connect my (Imate Jam) to my PC(winXPpro) it either freezes my pc, or puts up this msg.
USB device not recognised, one of the usb devices has malfunctioned, click here(opens up systems properties).
It does charge the Jam. well atleast the orange charge indicator lights up(i havent checked for actual charge).
The device drivers for my Jam are fine seeing as it still works when i connect with my original cable.
my original cable works fine, even if i switch straight back to it after trying to connect with the new cable.
I think the cable may be wired incorrectly eg postive and neg prolly fine but the data pins are screwie some how, sound like a reasonable guess?
Is there something else that im not thinking of/dont know about that could be causing the problem?.
bleh just typed all that and answered my own question. the data pins in the new plug are a little bit shorter than the power plug. I use a silicone case on my Jam which stops the plug from pushing in all the way by like 0.25mm. took off the case and bingo problem fixed.
I hate when that happens.
Ok well i might as well say that its a nifty little piece of hardware now that i got it working.
Which leads me another question, the reason i got this new cable was to be able to leave it in my bag and pull it out when i wanted to use my Jam like a 1gb usb card(1gb sd card). the times when i wanted to do this would be at university.
is there a way to make a pc recognise the jam like a usb drive instead of a pocketpc upon connection? i wont beable to install activesync on university pc's.
Thanks

Hi,
I've used a USB charger on all my phones for a few years now. Just plug phone in on my desk and no worries. However my new Defy doesn't seem to take a charge from the USB on my network device (it's not a full PC). However my HTC HD2 could get a charge from it so:
1. Is the Defy more power hungry that it won't charge from an ND (I assume NDs put out less power over USB than a PC)
2. Does it just not show on the battery on the Defy that it's charging?
3. Have I missed something simple? I've gone into USB connection and selected charge only. I can't install drivers on the ND though, could that be it? The ND hasn't said it's found new hardware either though.
Thanks in advance for advice
motorola has a notorious reputation on this, they require a usb driver to be installed for charging some of their phones...
i think there's some strange combinations at work about this but, just use a standalone charger and it should solve the problem.
Thanks. I thought it would be that.
Bit short of plug sockets at work but I'll figure something out
Another point to note is that the Defy is very fussy regarding USB cables. A lot of cheap ones will pass data but no charge.

Would you consider hacking a usb cable to make a charging lead? A standard usb lead plugged into a PC will try to enumerate with the PC before it starts to draw power from the PC. However if you hacked a usb cable and shorted the DM and DP lines on the phone side, the phone 'should' detect the cable as a mains charger rather than a PC, thus enabling charge without any drivers on the PC. It would be something like the attachment...
Thanks for all the replies. Although my USB cable wasn't cheap and was capable of charging an HD2 which must be more power hungry than a Defy, it turns out the Defy is really fussy. It's charging fine through the Motorola USB lead on my network device.
My USB loading experience
Hi,
just to share my exp:
- loading with most USB loaders: fine
- My Car loaders and my multi power adaptor with usb can load everything but the defy
- on Computer no problem (some say you will have better battery performance when loading on non Computer: I can´t see a difference)
- cable doesn´t change anything

I've bought a couple of USB cables from ebay. My Defy seems to connect and disconnect when using them, like it has a loose connection. If I use the Motorola one, of course it's fine!
I'm not able to get to the bootloader screen because the front usb port is not functioning on my unit. Has anyone been able to use one of the USB ports on the back to get to ADB and/or get to the bootloader? Is this a known issue with a workaround? I've done quite a bit of searching and have not turned up any solutions. Considering what is involved in shipping this back, I'd much rather figure something out. Thanks in advance for any help!
Edit: I should mention that I have used the adbon password and it does acknowledge that adb has been enabled. Just nothing seems to work on the front port. When I connect my Linux machine and run lsusb nothing shows for the unit. I have considered buying or making a USB-A to USB-A cable to connect my computer to one of the back USB ports, but I'm concerned about how these back USB ports are designed. Is it as simple as a built-in OTG cable? If so I'm probably fine. If it is more like a computer's USB port I could damage my laptop, my headunit, or both. I'd really like to hear if anyone else has had to deal with this. Unfortunately I haven't verified if the front USB will charge a phone. This is my next step.

My front USB also doesn't work. I even got mini to standard USB cable with unit, but plugging flash drive into it doesn't produce any reslt.
I also plugged extension cable to one of back USB ports and tried it (plugibg same USB flash) but it doesn't work either.
So I'm also confused.
Does that mean you are still running the stock ROM? I have been hesitant to install the custom ROM because they say you must be able to get into the bootloader even though I couldn't find a step in the process that required it.
Regarding the USB ports not working at all, you may find that you need to use a powered USB hub. I've seen reports of USB devices acting up due to the low power. This is one of the reasons I thought it might be safe to use the rear ports with my computer. (My first real test is going to be mangling a male-to-male USB cable so only the data lines are connected to see if I can get those rear USB ports to talk to the computer. I figure that way there is no chance of frying any circuits.. Each side already has its own power and I don't believe any signaling is sent via the power pins.)
On my unit (MTCB-KGL-V2.80), I have used a T-Mobile USB broadband modem successfully on the rear port, so I know rear ports are live. I did take it apart to see if something was obviously wrong with the front port, but nothing jumped out at me.
So I have a bit more information on my headunit. BTW, I have the BMW E46 model with MCU MTCB-KGL-V2.80.
On my system, both the front USB port and the rear 3G USB port are wired as device ports connected to an AU6258 USB controller (http://www.sunnyqi.com/upLoad/product/month_1403/201403162331285643.pdf). I don't remember exactly which USB ports they are connected to, but I believe the 3G port is connected to port 2 (pins 6 & 7) and the front USB port is connected to either ports 3 or 4 (pins 9 & 10 or 11 & 12 respectively). Nothing is connected to port 1 or to the upstream port. The other rear USB port is wired directly to the MTC_RK3188 board.
All three ports are wired with only four pins, so I'm concerned that none of them could work with the computer. The USB controller doesn't have USB ID pins, so does that mean that the 4 downstream ports are OTG and the upstream port is for a computer? Unfortunately I don't know the hardware side.

No I flashed Malaysk ROM from GPS SD card. No problems. Just follow instruction. I had luck that I didn't need to recover from USB.
Did you tried with USB powered hub? I don't have one to try it myself.

I checked on my Linux workstation with

plugging and unplugging all three USB cables and the number did not change. BTW where did you use the "adbon" command? The only place that I could even try was at Settings > Factory Settings. Regards Flint
Hi all!
My computers USB port was broken and it let all the electric through (don't know how to write these thing in english)
I connect my phone to the USB and don't know that.. then my phone only charge through computers usb and pc doesn't even try to recognize it.
Then i connected my microsd cardreader to same usb and i heard "puff" and smelld burning electric.
Phone does not smell like burned or anything. Working just fine.. it only doesn't work with data transfer.
So.. is it possible to fix by myself? like changing the usb dock https://ae01.alicdn.com/kf/HTB1xvUoMVXXXXaoaXXXq6xXFXXXf/5PCS-For-Xiaomi-Mi-Max-Hexa-Core-6-44-Smartphone-USB-Charging-Port-Dock-Connector-Transfer.jpg
Or is my phone bricked forever and i cant use it through usb cable?
i hope that you all understand my problem, it's hard to write these thing different language
Anyone?
Replacing the usb dock piece will probably fix your problem and isnt very hard to replace and isnt very expensive from aliexpress. I cant post links but if you go to youtube and search "mi max disassembly" it will show you how to take apart the phone and get to the piece. i have taken myn apart before and it isnt very hard at all. Hope this helps
Sorry, it's not clear to me. Is there a problem with the USB port on your phone? Or only a problem with the USB port on your computer?
You may want to try a different USB cable. Sometimes the microUSB adapters can get worn out.
Problem is on the phone. Phone only charge from usb. Settings are ok.
Same usb port broke my Canon also. It has warranty and its fixed now. It was same way broken than my phone.
Computers usb is fixed now.
due to my own stupidity, i had unlocked and installed twrp with a lot of effort, as the usb is decidedly iffy
i managed to use a file manager to import the requisite lineage rom and gapps, and then in my infinite wisdom stored them somewhere volatile - one mistake i won't make again
and so when i cleaned the device prior to a "new" install, i inadvertently lost the zip files, and now the computer refuses to recognise the device
no amount of forcing the right usb driver onit works, because i presume the computer does not know it's a flo
so, is there any way i can get it connected and push the roms to storage ?
my skills at the command line are limited, but i can follow scripts
this is sad, as i was soooooooo close to completing the install, after which the usb would have become redundant (i have a wireless charger and can wifi file across with a working system)
is this thus my very first brick ?
or can i trick the usb connection into working with the computer, or somehow wirelessly transfer to such a basic installation, or rig an otg connection (i have no cables that would seem to join micro-usb to any female plug to use a memory stick or sd card in adaptor)
thanks for any suggestions :fingers-crossed:
Get an image file from Google https://developers.google.com/android/images
Try going into TWRP and go into sideloading (can't remember exact menu - only used it once to get out of a similar problem), then try to connect USB lead to PC.
Run flash-all.bat on PC and that should at least get a system on the device.
Maybe...
thanks for the suggestion, but the sideload could place the lineage.zip instead if the computer would accept a usb connection - that's the problem: sideload can't work because the usb device is not recognised
my best bet would appear to be load the zip via otg - the twrp interface appears to allow that
i'll report back here if that works (once i procure a usb otg connector)
I was in a similar position once and couldn't get a normal USB ADB connection with PC until I tried TWRP sideloading which kicked in the PC connection.
Did you try it?
OTG was the next thing I was going to suggest

As the USB port is broken there is no hope that an OTG adapter would work because it can not function without the data connections, exactly like PC-USB. Have a look at the port's soldering, it may need some re-work. If the port's connectors are damaged then a replacement is very cheap.
:good:

i sprung the back and was going to attempt to reflow the solder in case it had a dodgy connection - but i noted that the actual usb connector looked like it had been stretched, and took to it with my favourite pliers and performed some creative metalwork by squeezing it
lo and behold! the otg connection worked, at least for long enough to transfer the custom rom
thereafter when i reassembled the case, the otg connection failed but now the usb link seems to be happy enough even though that makes no great sense seeing it is the same connector port, and the otg works on my other android devices
still, gotta take what you can get, and i am now the proud owner of a nexus 7 "flo" with lineage doing nicely
thanks for all assistances

Ahh this explains why my N7 - used daily - has never developed any USB port problems! I thought that this USB port's construction was rather 'weak' so preemptively I applied a simple reinforcement, have a look at the attachments.
It was 4 years ago....
