мне нужно мониторить один девайс, подключается через usb/lp0. так вот при чтении из порта, (например как head -c 10 /dev/usb/lp0 > dump.log)
я постоянно получаю в dmesg:
usb 1-8.1: USB disconnect, address 11
drivers/usb/class/usblp.c: usblp0: removed
usb 1-8.1: new full speed USB device using ehci_hcd and address 12

как бы узнать, это косяк девайса или есть возможность пофиксить перезагрузку драйвера?
