Hi

I have created a pacakge that installs driver for a usb device using DPInst.
The driver installs fine, however after I login from a standard user account, it gives me an error: "You must be a member of the administrator's group to install this hardware".
When I do the plug in the device from administrator account, it obviusly works fine.
The problem is that I cannot give users administrative rights and I still want them to to able to use the usb device.
(Note: the drivers I am installing are not unsigned)

Can somene please suggest a way to get around this problem?

Thanks,

Had the same problem with a Casio calculator driver. The certificate that was used to sign the driver had expired.
The driver installed fine and everything was dandy until you connected the calculator. You would then get asked for administrative credentials to load the driver.
In WinXP the drivers has to be signed with a certificate from a trusted CA to allow them to be loaded into the OS without administrative permissions. Microsoft says this is by design.

See Captain Planet's "sticky" about drivers at the top of the forum.
