Question about Electronics - Others
I have a Sigma MCR 300 USB 2.0 9 in 1 card reader/writer, and I have input a new SanDisk 2.0 GB memory card into the reader, from a new digital camera we bought. My problem is that the reader doesn't seem to recognize the card. I've tried to look for an updated driver, but the 2001 version seems to be the most recent avail. FYI...This reader doesn't have any problem reading from my former camera's compact flash card. Can you help?
Current Driver Info:
Driver Date: 7/1/2001
Driver Version: 5.1.2535.0
Current operating system: Windows XP Professional Version 2002, Service Pack 3
What I suspect here is that, the USB port that you are using is a USB 1.0 port, which has a lower voltage not enough to power on your Storage drive.
In this case, there are two things you can do,
1. Change the USB port you are using for the storage drive to a USB 2.0 one (Just keep Checking all the ports one by one in case you dont know which one it is).
2. If your Storage drive has external power facility, just plug it in an external power first, before connecting it to the system.
If there are no USB 2.0 Ports on your system at all,
then just go to any electronic store and tell them you want to buy a USB 2.0 Expansion card.
and if it is a laptop, A USB 2.0 PCMCIA card.
Install it on your system, and connect your external drive through it.
Hope this helps you out.

Tips for a great answer:
What happens when you tried to plug-in SD card to the computer?
Have you made any recent changes to the computer prior to the issue?
To make the SDHC be recognized by the computer, we need to ensure that the card reader works in Windows 7 first. Please check if the card reader is recognized properly by the computer and you have installed the driver for it.
Meanwhile, you can plug some other storage cards to the card reader and see how it works.
I would suggest you to refer the link below
A Secure Digital (SD) card may not be recognized on a Windows 7 based computer.
Uninstall all the Generic USB drivers and reinstall.
1. Open Device Manager.
2. In "Disk Drives" dropdown, uninstall the "Generic SD/MMC USB device" drive.
3. Restart computer.
4. Insert SDHC card.
Hope this helps.
