No. This also occurs after connecting the device while it's turned off. In this state, the device is connected. When, with its switch in the off position, I connect it, my log shows: kernel: [6125541.188647] usb 5-3: New USB device found, idVendor=10c4, idProduct=ea80 kernel: [6125541.188659] usb 5-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 kernel: [6125541.188667] usb 5-3: Product: CP2110 HID USB-to-UART Bridge kernel: [6125541.188673] usb 5-3: Manufacturer: Silicon Laboratories kernel: [6125541.188679] usb 5-3: SerialNumber: 0012EC89 kernel: [6125541.287283] hid-generic 0003:10C4:EA80.0011: hiddev0,hidraw2: USB HID v1.11 Device [Silicon Laboratories CP2110 HID USB-to-UART Bridge] on usb-0000:00:13.0-3/input0 mtp-probe: checking bus 5, device 12: "/sys/devices/pci0000:00/0000:00:13.0/usb5/5-3" mtp-probe: bus: 5, device: 12 was not an MTP device >Which signal?

Completion. urb->signr is set to 34 (SIGRTMIN), and that's the signal I'm getting. >Did you turn off the device while the URB was in progress, or was the device >turned off all along?
