The Cardreader init fails in about 50% of system boots, with the following lines: usb 1-6: unable to read config index 0 descriptor/all usb 1-6: can't read configurations, error -71 hub 1-0:1.0: Cannot enable port 6. Maybe the USB cable is bad? The patch let's the kernel stay in the loop, the cardreader is detected properly and the loop is never executed more than two times. The second call of usb_control_msg succeeds always. Maybe it was the developer's goal of the loop to fix such things? cu, Steffen --X1bOJ3K7DJ5YkBrT Content-Type: application/x-gunzip Content-Disposition: attachment; filename="usb-initfix.diff.gz" Content-Transfer-Encoding: base64 H4sICEuEwEYCA3VzYi1pbml0Zml4LmRpZmYAlY1BT8JAEIXPu7/iHTHrbstUCxRN6sGjYgh/ oJQpNOA22e2qF/67beECB6LJTGbm5Zv3NnVVQb8XweFQ2/CjyaSGyFC0cfUXOx8Fv47KxnH0 yd4XWzblFWksf9+gpdb6795itQt4CVtgBkoymmbjR1AcT6RS6n/B4q2xg9U4QTzLiLo6WeU5 dJo83KdQ/ZgizyWEEI59OLR4hn79WC5Wi/mglo1tu1werqNUQtQVRmf2CfFdL11Sa8fFvt+O XTtug7M4PczlL5TN5fZyAQAA --X1bOJ3K7DJ5YkBrT Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename=README USB-Cardreader (AU6375) init fix, Steffen Koepf, steffen.koepf@opaya.de --X1bOJ3K7DJ5YkBrT--
