Here's the sequence: . Pull the power cord of the scanner and reinsert. . Execute the scanimage command you provided. . After the command exits, pull the power cord and reinsert. Note that the light beam is at the wrong end throughout this sequence. Here's the dmesg from this sequence: [13073.710445] usb 3-3: USB disconnect, address 7 [13073.878285] usb 4-2: USB disconnect, address 8 [13073.878536] usblp0: removed [13074.272968] usb 4-2: new full speed USB device using ohci_hcd and address 9 [13074.446646] usb 4-2: configuration #1 chosen from 1 choice [13074.456623] usblp0: USB Bidirectional printer dev 9 if 0 alt 0 proto 2 vid 0x03F0 pid 0xC302 [13075.088607] usb 3-3: new full speed USB device using ohci_hcd and address 8 [13075.254830] usb 3-3: configuration #1 chosen from 1 choice [13075.847421] usb 4-2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1 [13151.363781] usb 3-3: USB disconnect, address 8 [13151.827293] usb 4-2: USB disconnect, address 9 [13151.827544] usblp0: removed [13152.228119] usb 3-3: new full speed USB device using ohci_hcd and address 9 [13152.395060] usb 3-3: configuration #1 chosen from 1 choice [13152.664607] usb 4-2: new full speed USB device using ohci_hcd and address 10 [13152.839115] usb 4-2: configuration #1 chosen from 1 choice [13152.846046] usblp0: USB Bidirectional printer dev 10 if 0 alt 0 proto 2 vid 0x03F0 pid 0xC302 [13154.038082] usb 4-2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1 Thanks.
