I use linux mandrake 9.0 , downloaded an compiled sane-backends 1.0.9 with the latest scanimage souce. If I use the scanner in=20 windows and then switch to linux, it works fine; but no chance if I do it directly after powering down the scanner. The debug output is: [sanei_debug] Setting debug level of snapscan to 2. [snapscan] usb_write Only 0 bytes written [snapscan] mini_inquiry: snapscan_cmd command failed: Error during device= I/O [snapscan] snapscani_check_device: mini_inquiry failed with Error during=20 device I/O.
