Hi All,
I am having problems writig data to a 64 MB direct
access device (LEXAR make). I use SG_IO ioctl provided
by SCSI Generic (sg) to access the USB Mass Storage
device. After issuing WRITE_10 command the SCSI genric
driver freezes. The linux kernel version is 2.4.20. On
the other hand SCSI READ_10 commands succeed using the
same ioctl.
Traces..........
usb-storage: queuecommand() called
usb-storage: *** thread awakened.
usb-storage: Command WRITE_10 (10 bytes)
