Hello, I have three USB controllers on my laptop, one on the left side of the system, one on the right, and one for the base station which has two usb ports when I dock. I think the USB controller for the base station is causing problems on my system and I was wondering if I could disable just that USB controller while leaving the other two running. When I compile USB into the kernel, I get error messages saying: "usb0: host controller halted" about once every two seconds. If I don't compile USB into the kernel and instead let usbd automatically load the kernel module, I get no error messages and my USB mouse works without any problems on the two USB ports on the laptop. However, it doesn't register when I plug it into the USB ports on the media base. From dmesg: uhci0: <Intel 82801CA/CAM (ICH3) USB controller USB-A> port 0x8c80-0x8c9f irq 10 at device 29.0 on pci0 usb0: <Intel 82801CA/CAM (ICH3) USB controller USB-A> on uhci0 usb0: USB revision 1.0 uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered uhci1: <Intel 82801CA/CAM (ICH3) USB controller USB-B> port 0x8ca0-0x8cbf irq 11 at device 29.1 on pci0 usb1: <Intel 82801CA/CAM (ICH3) USB controller USB-B> on uhci1 usb1: USB revision 1.0 uhub1: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub1: 2 ports with 2 removable, self powered uhci2: <UHCI (generic) USB controller> port 0x8cc0-0x8cdf irq 11 at device 29.2 on pci0 uhci2: (New UHCI DeviceId=0x24878086) usb2: <UHCI (generic) USB controller> on uhci2 usb2: USB revision 1.0 uhub2: (0x24878086) UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub2: 2 ports with 2 removable, self powered Any ideas on how to selectively tell the system to start a usb controller but not to start another?
