USB drivers

[John Bouman]

I know that they must exist but I can't seem to find the USB drivers for HP OpenVMS 7.3-1 running on an HP AlphaServer DS10L which comes standard with 2 USB ports? Can any one point me in the right direction? Thanks!

You're at the right site. Try http://www1.itrc.hp.com/service/patch/patchDetail.do?BC=patch.breadcrumb.main|patch.breadcrumb.pdb|patch.breadcrumb.search|&patchid=VMS731_USB-V0100&context=openvms:alpha:7.3-1 or "maintenance and support for Compaq products" "OpenVMS" Search for Alpha/7.3-1.

Either VMS731_UPDATE-V0600 or VMS731_USB-V0100 will provide drivers for the Phillips USB controller.

Take care with the USB drivers, they are probably the same as the 'USB early adopters kit' I had some fun with a few years ago.
There is a situation in which the driver jumps half a page down the kernel stack. If you have the default SYSGEM parameter KSTACKPAGES (1) and you are already more than half a page down the stack, you get a KRNLSTAKNV bugcheck...

IF this occurs the ONLY solution is to increase KSTACKPAGES.
