Thank you that worked.

I've had some dramas trying to get the DR5000 to connect to my PC which I solved by changing usb cable I then tried to update the firmware and got this error.

AVR device initialized and ready to accept instructions
Device signature = 0x1e9744
erasing chip
reading input file "prog\DR5000.hex"
writing application (158568 bytes):
Error: DFU_DNLOAD failed: libusb0-dll:err [control_msg] sending control message failed, win error: A device attached to the system is not functioning.

Error: Failed to set memory unit 0x00 (Flash)
Error: DFU_DNLOAD failed: libusb0-dll:err [control_msg] sending control message failed, win error: A device attached to the system is not functioning.

I have tried to factory reset but with no success.

Does anyone have any suggestion on how to fix this.
