Broadcom Smartcard Reader WUDF Doesn't Work after sleep
The Broadcom USBCCID Smartcard Reader (WUDF) version 22.214.171.1248 (32 bit) and 974 (64 bit) does not work after the laptop comes back from sleep mode. I can also see that in the device manager, the device becomes "Unknown Device" and its power state is D3. However, the problem dis-appears after the system is rebooted. After the restart the device is back to Smartcard Readers and its power state is D0.
Apparently, the issue seems to be impacting both 32 bit and 64 bit versions on Windows 7.
Many thanks for any help to figure out the reason why its malfunctioning sometimes.
