USB doesn't like to share an IRQ setting which may cause a constant reboot.

You didn't say which operating system although I think it is M$ NT+ so I
can't give you specifics on how to resolve the problem. But here are
some MS knowledge-base articles that might help.

XP: Q314068

Goto Microsoft.com, "knowledge base" under support towards the bottom of
the page, type in the article number or issue in search and go. Good luck.
