Are you sure you have the latest "Enhanced" USB 2.0 driver? You don't have a B1 or B2 designation, do you? Those are Beta. Go to Windows Update to be sure. If you must, manually update the driver and "Display a list". Select the non-"B" driver.
USB 2.0 cardbus adapters also require a power supply externally - especially on a laptop.
Yes - USB is hard-wired to sound and video, but Cardbus adapters may not be. It differs from laptop to laptop.
: I have bought an external USB 2 HD and a USB 2 PCMCIA card for my laptop, a Toshiba Satellite 4090 running Windows ME.
: The drive works fine with the built-in USB 1.1 port. On the cardbus USB 2.0 port, it will work for a few minutes, then it is disconnected and Windows asks me to insert a disk in removable drive D. When disconnected and reconnected, the same thing happens.
: I've read most of the old messages here and have tried the following:
: update BIOS, reinstall Windows with p\i options, reassign IRQ for USB 2 manually (USB 2 no longer recognised though USB 1.1 works on card), disable serial ports to free IRQs etc.
: All USB ports are always assigned IRQ 11, sharing with video, sound, PCMCIA and infrared port. Reassigning them seems impossible as they're hardwired together, and reassigning the USB ports of the cardbus card in Safe Mode works for USB 2.0 but not USB 1.
: USB mouse works fine on the PCMCIA ports. The USB controllers are Intel for the built-in one, NEC for the cardbus ports.
: Any ideas?
