usbquirks in grub.conf on RHEL-5?

[David Hobley]

Hello, 

I am building a HTPC and was recommended RHEL by a Systems Administrator friend. I am almost there, but current getting stuck with trying to get my Imon VFD device working; following a HOWTO for other Linux distributions I apparently need to specify the following in my /etc/grub.conf file: 

(all on one line, before the mail client wraps it) 
kernel /vmlinuz-2.6.18-53.1.14.el5 root=/dev/VolGroup00/LogVol00 ro rhgb quiet usbhid.quirks=0x15c2:0x0036:0x4 

However, when I do that and reboot, I get the following error in /var/log/messages 

May 14 12:26:51 htpc kernel: Kernel command line: root=/dev/VolGroup00/LogVol00 ro rhgb quiet usbhid.quirks=0x15c2:0x0036:0x4 
May 14 12:26:51 htpc kernel: Unknown boot option `usbhid.quirks=0x15c2:0x0036:0x4': ignoring 

Is usbhid.quirks supported in RHEL-5? Is there some other magic I need to know? 

Cheers, 
David
