hi
i have buy lenovo ethernet adapter for my surface rt, but i connot found arm drivers
thinkpad usb 3.0 ehernet adapter
is it possible work whit my surface??
If you plug it in and it doesn't work automatically, then probably not.
I don't know if you're running RT 8.0 or 8.1. On 8.0 there was exactly 1 driver available for worked with USB adapters that used the AX88772 chip, but I'm fairly sure they are USB 2.0. This driver was NOT included with the OS.
With 8.1 I believe there are two drivers that shipped with the OS, but I recall reading that they don't automatically install when a USB Ethernet adapter is plugged in, so you might try running the add new hardware wizard and select the driver manually. I still suspect these drivers are for USB 2.0 but I'm not sure. Perhaps you'll get lucky...
Try install this driver. Only for Win8.0.

Does Nokia N1 got OTG support? I have Tried to connect my USB Flash through OTG cable but doesn't work for me ....
Doesn't work for me either >_<
I don't have an otg cable myself (yet) but can you try to use USB Host Diagnostics (available in play store) and post the report?
FYI I got an OTG cable myself and it didn't work. I dug a bit deeper and found out that OTG is most likely not implemented because Nokia N1 is using legacy usb controller over usb C - see below:
Converting USB 2.0 OTG SoCs to USB Type-C
While existing Device, Host, and DRD devices can be converted to support the USB Type-C connection with some effort, it is not practical to convert existing OTG SoCs. OTG requires a new state machine using the configuration channel to support USB Type-C. Host Negotiation Protocol is used to swap host and device role for OTG, while Power Delivery communication is used to change roles for USB Type-C. Combined, these challenges preclude simple upgrades of OTC SoCs to USB Type-C. - See more at: https://www.synopsys.com/Company/Pu...esign-type-c-2015q1.aspx#sthash.Ri02Guwe.dpuf

The only chance to get otg to work is most likely preparing a kernel patch (are the sources even available?) to manually switch the connector to host mode and power the attached device externally
After a bit of hacking around I was able to enable usb otg on my N1!
I've had a look at kernel sources for device with similar SoC (Nexus Player) and saw an interesting debugfs entry. To my surprise it worked like a charm and immediately detected the attached usb hub with a thumb drive, it even powered the hub so I didn't have to use an external power source!
To enable host mode, the following command has to be enterted in root console:
echo A > /sys/kernel/debug/usb/dwc3_debugfs_root/otg_id
Caveats (will try to find a way to resolve them):
- after enabling host mode N1, won't charge from the usb port - a reboot is required to enable the charging again
- probably same is true for pheripherial mode (connecting n1 to a pc). In theory, changing a to b in the above echo command should bring the tablet back to normal mode but for some reason it won't charge without a reboot so I'm assuming that same is true for non otg usb connectivity. Will have a look at the sources and debug messages to find out what's going on

Thanks for your hard job.
I have tried on my N1. It is amazing that otg did work. However, the otg can not coexist with charging function as yours. Hope someone could find a solution.

Hey,
Are you on Android 5.1.1 or 5.0 ?
I've had a look at the code of the usb driver of the a phone with similar chipset (asus zenfone 5) and it seems that the source of the problem is that the tablet fails to detect an appropriate charger type, which could mean either that the otg cable does not support this or the code of the driver does not work properly with usb C. Was wondering if something changed around this after the update?

Hi, mine N1 is still running the android 5.0.
I am afraid Root is the prerequisite to hack otg. Unfortunately, root is not available on android 5.1.1 till now, so even the android 5.1.1 driver support it, that won't help.
Thanks,dude.
Yeah exactly for that reason I haven't upgraded my tablet yet
Finally caught the driver bug! W10 x64. Take one PC that would concurrently connect N10(Omnirom 6), N9 (rooted) and stock N5 and connect a Pixel C. Connects as a Pixel C in Device Manager under "Portable Devices" - enable USB debugging and W10 says "The last USB device you connected to this computer malfunctioned and Windows doesn't recognise it". Could write a book on the steps taken. Tried to add "Android Composite ADB Interface" via install legacy hardware and pointing to Googles USB drivers (v11) I get a no x64 compatible files error. Even cleaned out W10 driver store of relevant drivers via the command prompt ( and then discovered RAPR windows front end to pnputils.exe at https://driverstoreexplorer.codeplex.com/). Nexu5 with USB debugging + MTP connects perfectly haven't tried N9 or N10.
Any bright ideas?
Don't think this has any relevance with MTP working - Using Anker USB-C to USB3 cable with rounded edges on connectors - AFAIK this version has the correct resistor
download a copy of USBDeview for x64
open it, sort the list on vendorid
uninstall every driver with vendorid of 18d1
close the program, unplug all USB devices, reboot
make sure you have the newest google drivers on the pc
plug in pixel c and let drivers install, unplug pixel c and reboot
it should now work correctly
this routine has helped me every time i had issues with the pixel c and pc recognition
most of the steps came from wugfresh's nexus root toolkit advice on how to get proper drivers
i think what happens is drivers from other devices combine to create a situation windows can not fix so need to start over.
each device plugged in will get the install routine.
Hi,
Tablet: RK 3126
Manufacturer: Rockchip Fuzhou
Tablet OS: Android 4.4
Laptop OS: Win 10 x64
Problem: Not able to install drivers/ successfully connect the tablet to my laptop.
The tablet doesn't have a normal micro USB port, instead it has a 5 pin connector. Something like this. I cut a USB cord in half and managed to connect the tablet to the laptop. Now device manager shows "Unknown USB Device (Device Descriptor Request Failed)" which as I understand is supposed to happen with Rockchip tablets. Now, I cannot get further to this. I downloaded Rockchip driver assistant v4.3 and tried all variants of x64, x32 and win8, win7, vista, xp but nothing seems to work.
Please help if you have ever worked with Rockchip devices with Windows 10.
Thanks.
Turns out the USB cable was defective. What are the odds of that! Works great now
Now I have several Type C cable including two 3.1 (Belkin and Anker) cable.
All charge fine, but I realized 3.1 cable has problem on file transfer (computer cannot recognize), but all 2.0 type C cables work 100%.
It's probably H918 isn't compatible with USB3.1.
---- update ----
Install latest USB driver fixed the problem

Is there a question you're asking or is this just an observation?

My opinion.
The phone only works with USB2.0

I can confirm. However USB 3.1 cables work for transfers in TWRP.
I figured out why.
Make sure you have latest USB driver.
If you have LG Bridge, update to the latest driver.
If you installed LG United Driver, make sure it's 4.2.0
http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
After updated the driver, both 2.0 and 3.1 cable work properly.
I have 4.1.1 and it won't recognize my USB 3 cables, both from Anker... well, it won't recognize properly if I choose file transfer, but it works fine if I choose picture transfer or use them on USB 2.0 ports. any suggestions?

Try LG Bridge
BTW, the latest United Driver version is 4.2.0
Some crap with windows. It took me hours but I finally was able to get the usb 3.1 cable to transfer files. I couldn't tell you what I did though. It wasn't drivers though. It was all windows.
Is there any difference in charging times between USB 2.0 and 3.1, if you're using a type-C QC3.0 power adapter?

I'm also interested in this. I don't think there should be a difference.
I have a replacement cable.
I tried plugging in my device in my laptop using USB 3.0 port but it only charges my phone, it doesn't detect the MTP to transfer files. But when I tried plugging it in in the USB.. 2..0 port, MTP works.
My question is, is this because of the cable? Or is the A5 not supported by USB 3.0?

Mine works on a USB 3.0 port.
USB 3.0 should be backwards compatible to USB 2.0, so I think it's the cable. Maybe you could try again on a different pc? Just to be sure.
If you're using Windows check your device manager to see what it says, maybe a specific usb driver is needed?
i have same problem.
many time ago my phone (A5 2017) recognize with my laptop but after some update its not recognize in laptop but detect in office PC.
i do some work like change windows , reinstall add driver, use linux but not work in laptop. its now just work with one PC in office and other PCs not work. (
