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!
