I've noticed that many USB card readers are non-functional under Linux; according to the kernel developers, it's because relatively few of them implement the USB removable block storage class (protocol) correctly. While there are lots of expensive card readers that work with Linux, finding cheap ones is challenging.
I think, however, that I've found the ultimate *cheap* USB card reader that works with Linux: the "Tech-1 USB 2.0 CARD READER" at Dollarama. IIRC, it cost $2.
You'll almost certainly want to get a USB A-A extension cable for $1 or $2 at the same time, since the card reader comes with a 1" cable...

I've yet to see a card reader that *didn't* work on my linux box. Are you using a new enough linux (like Fedora or Ubuntu instead of years-behind RHEL/CentOS)?
Ya, the uber-cheap ones seem to work well. There's a cool mini 28-in-1 one I can get in for around $6. Your $2 is even better.

I have four N-in-1 USB 2.0 card readers here that don't work with any of Ubuntu 12.04LTS, CentOS 6.5, or OpenBSD 5.4.
Some reading online seemed to indicate that the problem is endemic, mostly crappy firmware implementations on the readers.
Oddly, most of the single-function card readers work well - it's only the N-in-1 style that seem to have problems.

It's *really* cheap... both in price and construction quality. But what do expect for $2?
