Okay, This is a horse of a different color (parallel port to USB adapter) [USB device]! dmesg tells us that you are loading two USB devices - one is a bidirectional modem driver cdc_acm Abstract Control Model driver for USB modems and ISDN adapters, the other is reported as: [ 30.968766] usblp0: USB Bidirectional printer dev 4 if 0 alt 1 proto 2 vid 0x067B pid 0x2305 (conflicts with "no devices found"?) [ 30.968854] usbcore: registered new interface driver usblp Looks like that's our USB printer right there? Try: $ locate usblp Stuff the path to the device file reported from slocated into $PATH below. $ echo -en "\rHello\r\f" > $PATH/usblp And you forgot to tell us what it is whining about? $ tail /var/log/cups/error_log $ tail /var/log/message Might look like this: Oct 28 20:02:38 honeypot kernel: [ 332.160000] usb 1-2: USB disconnect, address 8 And what does this tell you? $ lsusb Many times with USB printers an attach and unattach or power change will cause a disconnect.
