USB Problem!!!

I have a Flash Drive HP w320. It keeps trying to load but it doesn't.

What should I do? This is what happened...

I put 2 flash drives in to the slots and safari and itunes were running. I was using an old mac at the moment (500 MHz PowerPC G3). My mac just froze so I Force Quitted Safari and iTunes. My 1st drive(PEN DRIVE) was readable but my 2nd one(HP w320) did not appear and I waited 30 min. I gave up and I Relaunched Finder. It became worse because I could not see anything on my desktop... I shut down the mac by holding the power switch. After it turned back on, the pen drive loads but the HP w320 doesn't. It just keeps flashing its green light and been waiting for 4hrs!!!! Any suggestions wouold be helpful...

 

I Meant What To Do About The Flash Drives...


Never mind...Both of them work on Windows...

My usb mouse doesn't work either...

Do any of you guys think my usb ports just broke or collapsed? (If so, what should I do?)
