Pete, I can't get my netac flash drive working on db1550. Could you tell me what went wrong? I mount the usbfs as "mount none /proc/bus/usb -t usbfs". In /proc/bus/usb, I don't see "drivers", only "001" and "devices". Under /proc/scsc/usb-storage, there is file "0", which gives the information for this drive: Host scsi0: usb-storage Vendor: Netac Product: OnlyDisk Serial number: None Protocol: Transparent SCSI Transport: Bulk The output from usb-storage debug keeps showing "Bad target number", since the device->id is not 0 and the flags is 0. Any suggestion on this part? ...
