usb problem - port won't access 1 device, which does work elsewhere

Ok here's the background. I bought a soyo baybox that provides an upfront usb port and flash card readers. It connects via a pair of usb headers on the mobo. However, my computer is a dell 400sc (server) with no headers. To solve the problem, I cut the ends of the box cable and a pair of usb cables. Connected everything up and tried it out. The flash card slots work perfectly. If I plug a gamepad into the usb port that works fine. However, if I plug my sandisk usb2 memory stick, I get a device not recognized error. The stick works perfectly in other usb ports and other computers. Any ideas why?
 
how did you connect the two ends together? just wrapped them or did you solder them together? was there any shielding (metal braid/foil) in either cable?

I'm thinking its a power issue, or there is crosstalk interference in the splice area. Hard to tell without seeing it.

what's the baybox end connection? soldered? can you take the usb cable directly to where the baybox connection is? avoid any wire to wire connections...

My connections are made on a terminal strip from RadioShack (has 2 rows of 8 screws, so you can make 8 connections). I don't have the equip or skills for soldering 🙂 There was shielding on both cables. On the original cables coming from the baybox, the shielding was connected at the connector to the ground wire, so that's how I did my connections - just included the shield in the ground connections.

At the baybox end, it's a 8 pin connector - 8 pins coming up from the circuit board in the box and a 8 pin plug on the end of the wire. It seems to be a non-standard connection, so I couldn't just attach there.
 
By using the strip, you have added resistance to the cable, which
probably is the same as having a 100 ft cable.

You could have saved yourself hours of work and just gotten a
inexpensive POWERED USB HUB and the problem would be solved.
