I have a Linksys Wireless-G USB Network Adapter Model No. WUSB54GS ver.2.1 and only one of my USB cords works with it, and one with no markings except 'CBL' on the type A side. The two other USB cords I tried with it are USB 2.0's and they wont work with it, wont power up, nothing. I need to buy a 25 foot USB cable for this thing, but dont know if it will work considering the situation. What's going here, and what USB cord should I buy?
