Problems with using PS3 and PS2 stick together on a PS3

Hi all. Here’s something odd that I was hoping you guys could help out with.

I just got my TE SFIV stick this week for PS3. I also have my old ASCII PS2 stick that I have been using with a TAC USB adaptor with no problems. When I plug in my TE AND the ASCII, my PS3 freezes. When I use just my TE, it’s fine. When I use just my ASCII, it’s fine too. It’s when I plug in both that I run into problems. Any ideas as to what is causing this?

Thx, and apologies if this has already been covered elsewhere

Did you upgrade your PS3 to version 2.7? The problem may be covered here as many ps2–>ps3 converters are currently non-functional due to this upgrade:
