Seems confirmed that a usb low level error happens on first write attempt: [sanei_usb] sanei_usb_write_bulk: trying to write 10 bytes [sanei_usb] 000 F3 20 00 00 00 00 00 00 0C 00 . ........ USB error: error submitting URB: Device or resource busy [sanei_usb] sanei_usb_write_bulk: write failed: Device or resource busy USB error: could not clear/halt ep 1: Device or resource busy [pixma] WARNING:pixma_write(): count(0) != len(10)
I remember having seen this before for someone else, this happened when the usb port was going to power saving (generally after a few seconds) Could it be the case on system ?
