I have two different USB mice. One is a little portable one that has a wireless "dongle" that pluggs into the port. This one works fine. The second is an MX-900 (Logitec) that is a "bluetooth" mouse... but the unit itself shows up as a USB hub and a usb mouse in that hub. This (I believe) is due to the fact that the "base station" is emulating a usb mouse ... but also has the ability to show up as a bluetooth receiver (if you enable it). That function is not enabled on my mouse --- so it shows up as hub with a mouse attached to the hub. When the hub/mouse is unplugged, FreeBSD-5.3-BETA4 panic's hard but BETA2 did not. This may be a false hope ... I think I have seen this before, but I don't remember exactly. When it panics hard, I see "ums0 detached" (bright text) followed by "(null) at uhub4 <something something>" followed by a panic message an no dump. Here is the kernel messages for the working mouse: [3:2:302]dgilbert@canoe:~> dmesg | grep -i usb uhci0: <Intel 82801DB (ICH4) USB controller USB-A> port 0xbf80-0xbf9f irq 11 at device 29.0 on pci0 usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0 usb0: USB revision 1.0 uhci1: <Intel 82801DB (ICH4) USB controller USB-B> port 0xbf40-0xbf5f irq 11 at device 29.1 on pci0 usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1 usb1: USB revision 1.0 uhci2: <Intel 82801DB (ICH4) USB controller USB-C> port 0xbf20-0xbf3f irq 11 at device 29.2 on pci0 usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2 usb2: USB revision 1.0 ehci0: <EHCI (generic) USB 2.0 controller> mem 0xf4fffc00-0xf4ffffff irq 11 at device 29.7 on pci0 ehci_pci_attach: companion usb0 ehci_pci_attach: companion usb1 ehci_pci_attach: companion usb2 usb3: EHCI version 1.0 usb3: companion controllers, 2 ports each: usb0 usb1 usb2 usb3: <EHCI (generic) USB 2.0 controller> on ehci0 usb3: USB revision 2.0 ums0: PATEN USB Receiver, rev 1.10/1.03, addr 2, iclass 3/1 ums0: PATEN USB Receiver, rev 1.10/1.03, addr 2, iclass 3/1 Here are the kernel messages for the mouse attaching (obviously I can't show the exact detatch messages): uhub4: Texas Instruments General Purpose USB Hub, class 9/0, rev 1.10/1.01, addr 3 uhub4: 2 ports with 0 removable, bus powered ums1: Logitech USB Receiver, rev 1.10/27.04, addr 4, iclass 3/1 ums1: 7 buttons and Z dir.
