That it has a connector to go to the psu is surprising, because even that is
not necessary.
The card reader and front panel usb device are probably showing up as "mass
storage devices" right? It might be that XP is getting the drivers for both
devices mixed up.
Here is what you ought to try. Uninstall the card reader in Device
Properties. Then plug in the usb thumbdrive to see what happens. If that
does not work, then disable the card reader by right clicking on it and
selecting disable, which is probably listed under SCSI as a mass storage
device. Then uninstall the pront panel device and reinstall it in device
properties. Once it is reinstalled, plug in the thumbdrive to see if it will
work.
Post back here to let us know please.
Still equivocal. The power available through the front panel
USB ports on its own M/B connection is approx. 1.65 Watts. No
one is certain what other USB ports are on this connection.
Typically, each USB port is limited to around 500 mA, as GH
mentions. IIRC, the USB line uses 3.3 V.
The card reader is also drawing power from this circuit. The
proof will be the results from your solution. However, I would
have suggested physically disconnecting the card reader and
then test the thumbdrive.
