Comment 25 for bug 1371233

Experiencing a problem on xhci module with an Opticon Barcode Scanner NLV-1001 (ttyUSB device). After a few barcode-scan-triggers, it doesn't return from opening the device.

Tried:

- 3.13.0-35-generic
- 3.16.0-34-generic
- 3.17.0-031700-generic
- 3.19.1-031901-generic

Without USB3 (when disabled in BIOS) - ehci module is used, then, and no problems show up.

Could anyone tell me whether my problem with following trace is related to this issue?
Thank you for your help!
