XDA EXEC mini usb connector help

Hi,
need to know what type of mini USB is on the circuit ? how many pins?
thanks

All mini USB connectors should be created equal, usb (including usb mini) its what is called an idustry standard, thay have 5 pins total, same shape and size always, I wouldn't even suspect that some connector maker could took off any of the pins out, what surely should be, is that the connector must be a PCB mounting type, it would be a better idea to open the PDA, take off the connector and bring it with you when you buy the new one.
One easy solution -that I think someone in the forum has already mentioned- would be to use another device's mini usb conector (such as a broken bluetooth headset or a memory multicard reader).

Is the Synch/Charge Cable with an Orbit a standard Mini USB

I can't find the cable that came with the phone.
The headphone cable which fits the same hole is a very snug fit and doesn't look like a normal mini usb as has gold rails on both sides on the inside rather than a normal mini usb which only seems to have them on one side.
When I put a normal mini usb cable in, it feels a bit loose and whilst it charges my Orbit, it doesnt get recognised by the PC for synching.
Thoughts????

The actual body of the connector is a slightly different shape with the headphone connector being better matched than a normal mini USB plug, that said using a standard mini USB will not harm the device, I use whatever is available to charge my units, I would have thought it would sync to the PC though mine certainly do - Mike

Its designed that way.
Its quite a clever solution really - it allows the standard 4 pin usb cable to connect, but also has the additional pins for the special headphone connector.

I'm still stuck. My cable charges but won't let me synch?
Anyone got any other thoughts?

Where are you plugging in to the PC? try a direct connection rather than a hub, also make sure no other devices are connected using Active Sync. What version of Active Sync have you got installed on the PC - a few pointers to look in to - Mike

Generic USB-Slave to USBhost converter

Quite a lot PDAs supporting USB-host, but for only a few an adapters or appropriate cables from the manufactures are available.
As these devices support USB-Slave as well I would like to know if there's a way to convert the USB male connector (used as slave e.g. for sync with the PC) to a USB-host female in order to connect accessories (keyboard, mass-storage devices...).
According to wikipedia the configuration of the pins shouldn't differ too much for slave and host mode.
Pls. see attachement, that's what I found regarding this question. It's a picture showing a similar configuration (as new user I'm not allowed to post external links, thanks to ab21cn
from xdaflameusers)
But it's a male-to-male converter and furthermore a converter from "big usb" to micro (mini?) usb. As there're already standard converters for the different sizes of USB I would like to start with the biggest size and to buy the appropriate converter as needed.
Does anyone has a circuit diagram or any other idea for such a generic converter?

Try adapters made for Nokie N800 series
I had a Nokia 770 a couple of years ago. It came as USB device only with mini USB connector, but online I found how to upgrade the software to USB host, and use a cable adapter. The plans I found online involved a 9V battery and 5V voltage regulator inside a metal case (they used a penguin mints case). I built one of those, even using the penguin mints case, and it worked fine.
I have never seen any indication that my HTC phone would work the same, but I am guessing that it might, if the USB host drivers are available.
Google couldn't locate the penguin mints-based converter I originally found, but this seems to be a similar circuit diagram.
Edit: Found it!

thx
thanks for the links. but i'm a little bit afraid of connecting something to my pda which has an own power supply, the risk of a burn-out is given. i've got a nautiz x5 with 4400mA battery which should have enough energy to supply usb-power to connected devices.
I think I'm going to contact the manufacture of my device, maybe this works for me, but a generic adapter would be of use for anyone.
the chips used for usb should be of the shelf as i don't think each manufacture develops an own logic for usb... but this doesn't imply that the cabeling is standard too.
what the heck makes manufactures providing features in their products which the users can't take advantage of?

do you mean using keyboards and so on on ppc?
because it's so simple if ur phone has a mini usb plug (the one u plug the power adapter into). i found a cable that plug into that and plugs a normal usb cable in on the other side and blam been typing on my phone using a desktop keyboard. it depends how much power your device requires however. i wish there was some software to feed a video line out so i could watch videos on pair of vizors that wud be rad. all i can find is a mini-sd card converter now whats the point of that. guess i need an itouch

yes
primary i want to connect usb mass storage devices to my pocket pc. gamecontroller or keyboard would be a good thing too.
my devices doesn't have a standard usb plug, the only thing i got is a adapter from the properitary plug of my device to standard usb male connector, but this is meant for usb-slave use only.
the underlying qeustion is, if there's a way to convert usb-slave to usb-host using the same pins. if it needs an additonaly pin then i don't see a way to convert it as i don't know anything about the pins cableing of my properitary plug.
a week ago i found an adapter which was able to convert the male usb to another male usb... but it didn't work.
the problem is compareable to datatransfer between two pcs via usb - it's possible, but only using properiatry hardware and drivers...
so i think there's no way to solve this problem in a generic way.

out of interest, do you already have windows CE drivers for the device to act as a host and mass storage? I wouldnt mind them if you can point me somewhere..

how to check if my htc (touch2) ca use usb host?

USB 'B' to USB 'micro b'

I'm looking for a USB 'B' (the one that looks like a square) to micro to connect my s3 to a DAC. I know that there a micro to female USB, and USB A->B, but I'd rather not have to deal with all that for convince. Is there anywhere I can get the cable I'm looking for?
Or if anyone knows where I can get the 2 connectors I could make it myself, but I haven't found someone who sells decently priced USB connectors.

For the DIY soldering required end of things check out SparkFun https://www.sparkfun.com/products/9614 (the have other parts as well).
I got some from E-bay a while back as well. http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=140737641542&ssPageName=ADME:L:eek:C:US:3160
For all things cable related the answer is usually http://www.monoprice.com/. The definitive supplier of good quality reasonably priced cables.

I cant find any such cable, why not just use the converter cables?
all you need is a male micro to female usb type a and you can use your regular usb male a to usb male b cable
you can get it pretty cheap on amazon
you can try to make your own, if you already have these spare cables you will have to sacrifice them
here are the pin diagrams http://www.allpinouts.org/index.php/USB_-_Universal_Serial_Bus (the 11 pin micro usb model is used for hdmi out)
you might want to read through this thread as well as it asking the same thing you want (just a mini-b instead of b)
http://www.head-fi.org/t/628374/samsung-galaxy-s3-to-dac-usb-micro-b-male-to-mini-b-male

Hooking one end of a USB cable type to another end is uber easy.
Just splice the four wires together.
Tape it up if you don't solder.
Otherwise, the Headfi link posted above is a good start. Those guys are always looking up weird ways to hook up the phone to a DAC. Here's another good thread where I remember someone looking for something similar to what you are. It's buried deep in a zillion page thread though.

onoz ! i have twrp and boootloader, but no system files... HELP !

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....
