USB - Githubissues

underscore-bama commented 8 years ago

I've installed the rules and I still can't manage to get a USB signal in Download/Firmware mode. Just, "RuntimeError: USB device not found." Any ideas?

Lekensteyn commented 8 years ago

Can you post the full output as well as the output of lsusb (does it contain your LG device)?

underscore-bama commented 8 years ago

Output.

~/lglaf $ ./lglaf.py
Traceback (most recent call last):
  File "./lglaf.py", line 388, in <module>
    main()
  File "./lglaf.py", line 366, in main

    return USBCommunication()
  File "./lglaf.py", line 208, in __init__

RuntimeError: USB device not found

Yup.

I also updated 42-usb-lglaf.rules with the 633a device id and get nothing.

Lekensteyn commented 8 years ago

Please add the output of lsusb -vd 1004:633a, I guess that the detection of the endpoint number is wrong. Can try the ep-matching branch?

ep-matching branch throws the same error.

Lekensteyn commented 8 years ago

Your lsusb output indeed shows that the hard-coded endpoint numbers were incorrect. The ep-matching branch should work now, I had a stupid typo:

Sorry. Still throws the error. I've checked everything to make sure it's up to date and everything is. Strange.

That was obviously not tested nor reviewed by myself... Have another try with the updated branch that applies the following patch:

Lekensteyn commented 8 years ago

Only one program can use the USB device (lglaf or sonethiing else). Can you reproduce it after removing/re-inserting the device?

underscore-bama commented 8 years ago

I did that and then just did it again. I can't find another program that could possibly be trying to use it.

I think it might have something to do with claiming the interface before setting configuration (having to do with pyusb)?

Lekensteyn commented 8 years ago

It could be a kernel driver (check with lsusb -t) too

I think you might be right?

So ep-matching branch works on Windows. It's obviously a driver related issue in Linux. LAF still locks everything up though. Guess you can close this. Same with partitions.py.

On Linux, try sudo modprobe -vr cdc_acm (see the Driver= field).

I have finally gotten the chance to test my changes. The EP matching logic was still broken, but now it is fixed in f2792e6. The "Resource busy" issue is fixed with 688e0f3.

Can you confirm this? (The changes are merged to master)

I have not had a chance. Fedex picked the phone up this morning. Should have a replacement by Thursday to check for you.

The Resource busy error is fixed, however "Hello I'm LAF" shows up for any commands. So I guess LG has found you out.
