Hi Bob, Recently I bought an IR device (irTrans) which uses the usbserial interface. To my dismay I've seen that its operation interferes with that of the RK USB driver.
After tracing the trouble, it is clear that it is *not* the irTrans (software) fault: in fact, the interference does happen with the usbserial device itself. So here is the problem: First plug a usbserial device into an USB port. Then plug also the RK-USB and mount it e.g. at /mnt/karma2. So far so good, the RK interface works perfectly, for hours in a raw. Then just open somehow a usbserial device (e.g. cat /dev/ttyUSB0). After a (variable) short period /mnt/karma2 is no longer accesible. Tracing the problem further reveals that the RK usb_storage device is unbound and rebound every few seconds. So at any point in time you can find a right device and mount it correctly, but in a few more seconds, the device gets unbound/rebound and your moint point gets broken... Syslog clearly shows the process: 'USB disconnect, address N', followed by 'new high speed USB device ... address N+1', and so on every few seconds. I've tried with a couple of other usb_storage devices, and this problem does not happen, so it looks like the (main) issue is in the RK code of usb_storage. Any idea? Best, EV. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
