CrunchBang Linux

I troubleshoot a lot of different computers, and I found #! to be a great lightweight OS for testing basic hardware functionality (wireless cards, ethernet, audio).

However, sometimes hardware doesn't show up and I don't know whether it is because the device is defective or crunchbang doesn't have the drivers for that hardware.

So my question is: In Windows, you have a device manager which tells you if there is any hardware that isn't accounted for with a driver. Is there a similar thing for Crunchbang? And once I know what it is, what is the step-by-step process to get said driver?

A note: this isn't for rare/uncommon hardware. I had a broadcom wireless card in a laptop that wasn't being detected. I thought it was defective, but it's just the lack of driver support in #!. I figure Broadcom wireless cards are as common as Atheros, as those are the only 2 most common chips I've come across.

Is there something like a driver package that supports a range of common hardware?

Anyhoo, would appreciate any help, and thanks!
