The card reader for the 2GB chip for my R4... sucks. When I plug it into my computer it'll open up like everything else USB-y and be fine. Then, at random it will no longer be detected and I'll have to eject the device and plug it back in. I didn't really mind at first because I was only doing it every so often, but since I've been messing around with my own custom themes and removing some apps from the chip I was trying and didn't particularly like... well; it's gotten a bit irritating. So I was wondering if I could just purchase any USB/Micro SD card read and it would be fine? (Assuming that the one that came with the R4 isn't special in some way. Which I highly doubt, but it's safer to just ask the dumb question first than waste money/time asking it later!)
