One of the neat things with HTC Windows Mobile 5 devices on Windows Vista is when you activate the Wireless Modem over Bluetooth, Vista will just see the device and automatically detect it as a modem.
When you plug the device in to a Vista PC using USB (having first enabled Wireless Modem over USB on the phone), you may find that it won’t be recognised.
A solution can be derived from http://support.microsoft.com/kb/837637…
If you grab your standard HTC USB Modem INF file (you can grab a copy here if you don’t have one to hand) and add the emboldened lines below into the relevant places…
[Modem1.NT]
DriverVer=05/13/1999
include=mdmcpq.inf
CopyFiles=FakeModemCopyFileSection
…
…
…
[Modem1.NT.Services]
include=mdmcpq.inf
AddService=usbser, 0x00000000, LowerFilter_Service_Inst
…
…
…
[Modem1.NT.HW]
include=mdmcpq.inf
AddReg=LowerFilterAddReg
Save the file out under a new name, and when Vista starts looking for the driver, tell it you want to point to a specific location. If it finds this file, you should find that Robert’s your father’s brother!
Have a happy Christmas – see you in the new year!
