Hi ! We have two Dell PowerEdge 2950 which only have USB mouse & keyboard, therefore I'm using a USB to PS/2 converter to get the KVM switch to work with the servers. When I boot default FreeBSD-6.2 kernel then the system detects the usb converter : ukbd0: CHESEN PS2 to USB Converter, rev 1.10/0.10, addr 2, iclass 3/1 kbd2 at ukbd0 ums0: CHESEN PS2 to USB Converter, rev 1.10/0.10, addr 2, iclass 3/1 ums0: 5 buttons and Z dir. If I build a new kernel with GENERIC configuration, then the converter isn't detected and the keyboard doesn't work. :-( FreeBSD 6.2-STABLE #0: Tue Jul 17 10:46:46 CEST 2007 root@hostname:/usr/obj/usr/src/sys/GENERIC amd64 Here is more information form "dmesg -a" : uhci0: <UHCI (generic) USB controller> port 0xcce0-0xccff irq 21 at device 29.0 on pci0 uhci0: [GIANT-LOCKED] usb0: <UHCI (generic) USB controller> 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: <UHCI (generic) USB controller> port 0xccc0-0xccdf irq 20 at device 29.1 on pci0 uhci1: [GIANT-LOCKED] usb1: <UHCI (generic) USB controller> 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 0xcca0-0xccbf irq 21 at device 29.2 on pci0 uhci2: [GIANT-LOCKED] usb2: <UHCI (generic) USB controller> on uhci2 usb2: USB revision 1.0 uhub2: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub2: 2 ports with 2 removable, self powered ehci0: <EHCI (generic) USB 2.0 controller> mem 0xfc800400-0xfc8007ff irq 21 at device 29.7 on pci0 ehci0: [GIANT-LOCKED] 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 uhub3: Intel EHCI root hub, class 9/0, rev 2.00/1.00, addr 1 uhub3: 6 ports with 6 removable, self powered uhub4: vendor 0x04b4 product 0x6560, class 9/0, rev 2.00/0.0b, addr 2 uhub4: multiple transaction translators uhub4: 4 ports with 4 removable, self powered And here is some from "usbdevs -v" : Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb1: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb2: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb3: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 powered port 2 powered port 3 powered port 4 powered port 5 addr 2: high speed, self powered, config 1, product 0x6560(0x6560), vendor 0x04b4(0x04b4), rev 0.0b port 1 powered port 2 powered port 3 powered port 4 powered port 6 powered The usb to ps/2 converter is on the /dev/usb3 port 5. Is the support for this converter removed from the kernel or is this a bug ? Regards Roar
