I cannot install the driver for HM1 Android phone when connecting the phone to the PC (win7 64bit) with USB debugging connected. I used several driver packages (for example here). If I look at the device manager I see the following hardware id's for this unknown device: USB\VID_2717&PID_1228&REV_0255&MI_02 USB\VID_2717&PID_1228&MI_02 If I look in the driver packages, I don't see this idea's and there no driver is found if I try to install that driver. With Google I only find 1 similar case, but no answer. I can use SP flash tool without problems. I can also use the phone as storage device without problems. edit: ADB is now also working. What is going on and how can I solve this ?
