I have an old eMac that I was given with Ubuntu 10.04 LTS on it. The keyboard and mouse seem to work, but my flash drive won't read, nor will discs in the CD/DVD drive. It does not have a wireless card, so I bought a Wireless USB Adapter and it doesn't work, either. What do I do to remedy this? Thanks in advance for any help.

Oh, also, when I try to open the disc drive, it closes automatically. This is a minor issue, but if anyone has any insight, it would be appreciated. Thanks!
