I am trying to troubleshoot my Belkin 2 port USB KVM on a 2.4.20 kernel. This model is a pure USB KVM - no PS/2 plugins at all. I am not a developer/programmer, but I think I understand the basics fairly well....
Details:
- There has been a report (not by me) of this device working fine with Red Hat -
Linux version 2.4.20-19.8 [EMAIL PROTECTED]) (gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)) #1 Tue Jul 15 14:59:09 EDT 2003
- Gentoo linux - 2.4.20-r7 sources. My Kernel:
Linux version 2.4.20-gentoo-r7 ([EMAIL PROTECTED]) (gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r1, propolice)) #4 Fri Sep 19 00:21:32 MDT 2003
- boot options hdc=ide-scsi acpi=off
- edited USB .config entries:
# USB support
#
CONFIG_USB=y
# CONFIG_USB_DEBUG is not set
CONFIG_USB_DEVICEFS=y
# CONFIG_USB_BANDWIDTH is not set
CONFIG_USB_LONG_TIMEOUT=y
# CONFIG_USB_EHCI_HCD is not set
CONFIG_USB_UHCI=y
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
CONFIG_USB_HIDDEV=y- NO USB stuff as Modules

------------------------------------------------------ no change to lsusb -vv After KVM plugged in
So, not sure what to try next. The KVM works find in Windoze 2K.
Thanks for any and all help.
