Hello,
I work for a L-3 Technologies division in the IT department. We just recently (within the last month) upgraded our SEP Management server to Ver 14 MP1 build 2332. We have upgraded two laptops on our network for test purposes and they're the only two machines currently showing this issue. Since that upgrade we have had problems adding/enabling Device Hardware exemptions to the Applications and Device Control Policy our Corporate office gave us. I may just have to end up talking with them but wanted to also try the forums to see if there was a known bug.
We usually just plug in the USB device drive (Flash drive or external, etc.) to a client machine and the device would disable via the policy. We then go in to Device Manager and go to the properties of the disabled devices. Some of these have two drivers (one for CDROM and one for drive) that we copy the Device Instance Paths for. Once we'd add them to the exemption list the devices would eventually be enabled (might take 10 mins to a half hour). Since we upgraded the SEPM console though the two laptops that are in our test group can't get any of the device drivers to enable and install. Is there a known bug with this SEPM and client versions concerning exempting devices?
