USB PRO 900HB not working on Win 7 - Unknown Device


I received the XBEE PRO 900HP dev kit, it works fine on our Surface Pro 3 tablet (Win 8.1) but when I plug it in my Windows 7 T450s laptop it doesn’t work. I always get “Unknown Device”.

I installed the Digi_USB_RF_Drivers.exe, even tried to manually select the driver without success

Thanks for help

Try powering from an external power source.

Not working either

Initially I had Kaspersky Antivirus on my laptop and I removed it because it seemed to be the cause of my problems.

Unfortunately it didn’t solved my issue but this morning I tried to connect another board from my Dev Kit and this one is detected and installed correctly!
