Am Using Libusb 0.1 to test my printer code. The code runs as expected
with 2.6.32 kernel in debian 6. However, After debian 8 upgrade we
notice that printer responds for very first read operation after reboot,
For rest of command executions READ fails with*ENODEV*.
By doing this, I lost communication with the device
|1. USB_OPEN()
2. Claim the interface
3. USBBulkWriteOnEP (FW version request fro my device)
4. Release the interface
5. Claim the interface
6. USBBulkReadOnEP
7. Release the interface
8. Usb_close()
9. Loop on GOTO1.

*However, if i insert USB_RESET after every read operation the command
work..*
