The crash dumps are not very specific about which USB driver is bugging out. There may be many a reasons for it. But the first notion goes to this one:

Code:

Try to update it. If there is no feasible updates, uninstall it.

Also the Suyin USB 2.0 Webcam driver ....

Code:

Update is needed here too. But no abailable update is there in neither SUYIN nor OEM. So disabling it will be a good test.

Lastly ....
