Open Bench Logic Sniffer / Re: Unable to update PIC, says not found
USB Keyboard issue solved.
I finally found a good advice on SevenForums
It appears that for some magic reason the file C:Windowsusb.inf vanished.
I had to recover it from C:WindowsSystem32DriverStoreFileRepositoryusb.inf_amd64_neutral_153b489118ee37b8usb.inf
Once the backup file has been copied in the right place, forcing a new device detection in Device Manager discovered again the keyboard.
I will see now if it occur again whenever my LogicSniffer requires a new upgrade :D
Hard week :) !

Open Bench Logic Sniffer / Re: Unable to update PIC, says not found
The KB was originally connected to a hub but I also tried it direct (KB brand is APM VID 04F2 PID 0111). I also tried a Labtech KB (0603 00F2).
While I agree that the HID driver is standard, I have a restoration point that match the initial connection of the OLS and called "Microchip Technology Inc. Ports (COM & LPT)". I bet this one occurred when I connected the OLS first and the COM driver got installed (I remember seeing during the installation something about Microchip CDC).
What I also noted when plugging my USB KB on another W7 PC is that the device when it installs correctly get up with HID/VID_04F2&PID_0111 while on my PC it gets on USB/VID_04F2&PID_0111.
Very strange. Device is seen and somehow recognized as a "USB Keyboard" as it appears in devmgmt but not recognized as a HID device....
Something got wrong in my registry or something like this and unfortunately I cannot restore ...
I appreciate your concern.

Hi Ian
Yes, "USB keyboard" appears as "Other devices" with the yellow triangle icon and status says drivers cannot be loaded.
I tried to restore my system to a restoration-point before I plugged the OLS, but for some reasons W7 can't perform  the restoration, claiming about anti-virus locking a file although I did disabled the anti-virus.
Having to re-install W7 each time I do an OLS update is not really an option :( ;)

I had the same problem (win7x64).
Following your advice I disconnected all my USB peripherals including :
- FTDI USB/TTL adapter
- Mouse
- KB
And PIC upgrade ran fine
One was conflicting, I don't know which one...

But now I have another big problem !!

My USB KB does not work anymore.
I tried another one which does not work neither whie both KB works well on another PC

Apparently the operation have messed up my windows KB driver

Any idea would be appreciated.

Thanks
