USB card reader not working with XP x64

Jun 14, 2009 4:21AM PDT

I have a generic usb sd card reader. I have been running the 32-bit version of XP but have added the 64-bit (dual boot). The card reader works fine when I boot the 32-bit version but not when I boot the 64-bit version. The card reader does show up in the device manager but It does not show as a "drive" in "My Computer". Also I do not get any pop up when I insert the reader. I also have a PNY memory stick and it works fine under both 32 and 64 bit OS. The motherboard is an ECS K8M890M-M. Is it the 64-bit OS or the MB drivers or ..... What should I look at to figure this out?

All other USB devices that I have seem to work fine in both 32 and 64 bit OS.

Sorry about the cross post. But I did not get any responses at dslreports. I have another card reader (for smart cards not sd cards) and it works. I also have a memory stick that works. The puzzling part is that it works for 32-bit but not 64-bit. I looked at the USB drivers and the 32 driver is 5.1.2600.0 7/1/2001. The 64 bit driver is 5.2.3790.1830 10/1/2002.

Just keep trying adapters, readers and

The other USB ports. Be sure to unplug, count to 20 and plug into that other port as a test.

Not everything works and in this area of "cheap stuff" there is no one home at the maker to give us drivers.

No luck

I have tried it in all the the available ports and it does not work in any of them. However when I plugged it into an low speed external usb hub I got a warning that the device can perform faster if it was connected to a high speed (2.0) port. This is an SD card reader. I do not have any other SD readers. All of the other USB devices work with the 64 bit OS. The perplexing part is that it work on the 32 bit OS and the 64 bit OS does see it but just does not assign a drive to it. I experimented with adding usb devices in different orders to see if the card reader was reserving a drive letter. I found that my memory stick would be assigned the same drive letter regardless as to if the card read had been plugged in before the memory stick. So again the OS sees the card reader but does not assign it a drive letter.

my usb card reader experience
Jun 20, 2012 10:15PM PDT

i have several cheap card readers and found some work on some computers but on my windows xp computer only one worked. i tried to solve this problem with drivers etc but found the problem was the usb extension cable i was using. when i plugged the various card readers directly into usb port of computer they immediately worked. the cable works fine with my printer and one of the card readers. it is worth a try and something you would not imagine would be a problem. most of these card readers do not require a driver at all.

The real problem is XP 64 BIT

It's not supported so readers and larger memory cards will fail.

I have not heard of any company stepping up to address this.
