Error on Raspberry Pi, Kernel 4.1.12-v7+

[oleksii-frolov]

Steps to reproduce:

• remove cdc_acm driver
• install xr_usb_serial_common driver
• execute: setserial -a /dev/ttyXRUSB0

and we can see an error xr_usb_serial_ctrl_irq - urb shutting down with status: -2 in kernel log

[oleksii-frolov]

OK, actually in this fork there is no such error.

[Kutashov]

I have the same issue, regardless I used this fork or original xr driver. Have you fixed this somehow?

[ReindeerFan]

Now this error has become to my raspbian too, any ideas Kutashov? I can still randomly access data, but I'm afraid of lockups.

[Kutashov]

Unfortunately, no.

[ReindeerFan]

Beware of this driver, it works okay when reading data with those errors, but my raspberry died and rebooted randomly.

• kernel: [***] usb 1-1-port2: over-current change

That's why I won't risk it and have unloaded the module, if not reading data.
