First of all let me tell that I know very little about computers so I hope my terminology is correct. I bought my daughter a new computer 11 months ago and she is now having problems with the memory card reader. This is a Compaq Presario SR1603WM that came with CD-RW/DVD combo drive, 9 in 1 memory card reader USB interface,two USB external ports, windows xp, microsoft service pack 2. (anything else you need to know, just ask). Several months ago had a trojan virus while using Norton antivirus and am now using AVG and last scan showed no virus. The memory card reader has been used since then with no problems. A few weeks ago put the memory card in and it showed nothing. Looked under "my computer" and the only device with removable storage showing was CD/DVD. I tried troubleshooting on HP website and so far none of them have worked, including physically disconnecting the reader and reconnecting, reinstalling drivers and software, ensuring all devices are enabled, and compaq recovery (nondestructive). The only thing that changed after all that was in device manager under usb serial bus controllers there is an "unknown device". I ran the pc doctor and the report had "removed device: usb mass storage" (this was prior to unknown device showing up". Our IT guy at work suggested doing a recovery using the recovery disks, which I have not made and dont think I want to attempt on my own. Other suggestions have been that I have spyware that is messing it up but I have adaware and spybot and have ran both with nothing showing up. Short of having a shop fix this, I dont know what else to do. Any suggestions?
