alcor micro usb card reader what is it for

So, not sure if they 'fixed' something or the installing process of the driver itself did the trick. I read the version notes and it only says this driver is to support more HP models. So, went ahead and installed this new driver, reboot, first time insert of SD Card worked (as always), eject, re-insert many times.works fine. I had the v1.0.14.52 August 2010 driver installed.went to HP site and there was never (Dec-2010) v1.0.23.67. The USB Card Reader (as posted) in this HP DM4-1265DX is Alcor. Please let me know your thoughts or what to try ? Note, USB sticks, even USB external HDD have no problems. This is not a super critical issue but having to reboot to get SD card to work is a pain. In device manager I did right click and try update driver.Windows came back and said this was latest I have installed. I then uninstalled MBAM and guess what.problem went away. I did stop service in Task Manager and no change, did a uncheck of MBAM in MBAM for protective no change, did a right click on MBAM icon in tray to not have start at Windows, reboot, worked first time but then same error.

I found a thread on the Microsoft Community Forums (Googled) where person had same problem and found to be the MBAM Service. If we reboot the machine it works fine for first time again, any retries and no-go. Opening properties it says that the driver cannot be loaded because there is already an instance in memory. A re-insert gives us a bad 'bong' and when we look into device manager the Alcor Micro USB 2.0 Card Reader has yellow exclamation point. We noticed that when we insert a SD card it works on first try.

This thread is about four HP DM4 laptops we have. Had one issue on the Lenovo B570s in that MBAM conflicts with the Lenovo Security Center & Port Blocker Software.we are going to uninstall the Lenovo stuff and ems this is known issue. OK, installed MBAM PRO on a lot of laptops.DELLS, HPs, Lenovos.
