Not detecting Logitech Unifying Receiver after make logitech_install

[gracelee]

Hi I have been working on this mousejack with my logitech unifying receiver U0007.
I did 'sudo make logitech_install', and this gave me the following error:

Then all of sudden, my logitech mouse stop working and it is disconnected. So I checked whether the dongle is recongized by my ubuntu with 'lsusb', but it seems like it is not recongized well.

Does anybody know why this happened and how I fix this issue?

Thank you all

Same here. It does not start in "research firmware mode".

Nevertheless I managed to return the firmware using the prog/usb-flasher/logitech-usb-restore.py XXXXX.hex

I opened the http://chilp.it/3465237 using ResEdit and extracted a file looking like:
:0A00000002038A0080FD05264A2253
:07000B0080FE75B5FF8025A2
:0700130080FE80200217ECC3

Renamed it to .hex and restored it successfully.
lsusb shows it as Logitech, Inc. Unified Receiver again.

If anyone knows why the problem appears, please let us know.
