Have something strange going on with one of my USB ports. If a memory stick

is inserted, the computer gives the normal double beep sound. However, the

drive is not accessible, nor does it show up under device manager. When I

remove the mem stick (it does not show up under safey remove hardware) the

computer double sounds again. Now, if I look in device manager, a mass

storage device is now present. iAlso through trial and error I have

discovered that my 4-slot memory card reader works fine, until a mem stick

is placed into this particiular USB port. If a mem card is in place, the

active light turns off when the usb Mem stick is inserted. If the mem stick

is removed the card read is working again. Through device manager I have

uninstalled all composite devices and rebooted for the re-install. I have

also tried booting with the mem stick in the usb port both with and without

the unistall \ install. All other usb ports are functioning, the mem stick

works on other computers and no mem stick will work int this particular usb

port.

 

Thanks in advance for the help!

I think the mass storage device that appears after removal

of the flash drive is the internal card reader.

 

The whole effect sounds like a power problem. The card reader

draws power near the limit and the USB port in question shares

it's power with the internal port the card reader is attached

to.

 

No other solution here than replacing the card reader or

just don't use the USB port in question for devices which

need power from the USB port. Using this port for a self

powered USB hub should work.

Thanks Uwe.

 

This port used to work. Also, if I leave a mem card in place, install and

remove the mem stick, two mass storage devices show up after the removal of

the thumb drive. I certanly agree as I have other usb ports, but sometimes

it's the challenge and it just kinda makes you mad! Thanks Danny
