Greetings: I have been trying to get a recently acquired Cardbus based USB 2.0 card working under 2.6 for the past weekend. It's not going well.
Everytime I plug the card into the computer, the entire PCMCIA system just dies, taking my network connectivity with it. I have to do a power off reset to recover. The cardbus card is based on the ALI USB chipset. This shows up as both an EHCI and an OHCI device under 2.6.11.5. My laptop, an older HP Pavilion N5150 has a UHCI based chipset: 00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) 00:04.0 CardBus bridge: Texas Instruments PCI1420 00:04.1 CardBus bridge: Texas Instruments PCI1420 00:07.0 ISA bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02) 00:07.1 IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 03) 00:08.0 Multimedia audio controller: ESS Technology ES1988 Allegro-1 (rev 12) 01:01.0 VGA compatible controller: S3 Inc. 86C270-294 Savage/IX-MV (rev 11) 02:00.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41) My ethernet card is a generic cardbus device. When I insert the new USB 2.0 card, the kernel reports that it's killing off IRQ 11. Here is the actual dump from dmesg: Mar 20 18:38:13 port2 kernel: irq 11: nobody cared!

Controller is probably using the wrong IRQ. Again, when the USB card in inserted, the entire PCMCIA system shuts down and remains unusuable until powered off. Kernel is stock 2.6.11.5. I also tried with 2.6.11, 2.6.10, 2.6.9 and 2.6.7 - same result.
