USB2.0 external HDD interface card

Specs: Windows XP
I have a maxtor One touch External HDD, that has to stay portable. It has an interface card that has a Cypress CY7C68013-100AC, FX2LP EEPROM chip set up on it. Cypress has provided me a zip file AN65209 that has a sample firmware in a Bulkloop.HEX file with directions on how to install it. A bit unsure about what to do with that, because of the sample part. I was wanting to know if any of you programmers could tell how to look into interface card and see what firmware maxtor has installed in it, I suspect that it is at fault for my problem I am having, the 120gig drive showing in win xp Pro device manager as usb drive not the normal s/n and I can't access it in any way. In the USB tree is is listed as maxtor one touch. The drive checks out good as a secondary. I have narrowed it down to the card, it seems that if F/W doesn't work it will be a bad card. And is there any firmware out there that I can replace maxtor's with that will make it work? Seagate is of no help at all. I have posted under "General" and can give more here if needed. I can't afford to buy another case and am trying to use this as a learning tool also. Thanks.

Your post is not clear. How is this external hard drive connected to your computer?

Thanks "OtheHill" it is usb 2.0 and all that works fine, on the pc's end. It is something in the interface in the case between the PC and the 120gig inside the case, I suspect a firmware problem. I used the cypress control panel and can see the vid &pid so I think the card is good, not sure.I have some screen shots of the the problem but not sure how or where to post them. thanks.

It may be easier/simpler to replace the usb housing, the current case in which the drive is enclosed?

I had a Segate similar to the Maxtor, and that lost the controller card... Long story short... Transferred the drive to another externally powered case (one with a decent cooling fan too) and it works fine. It still is i/d'd (the volume name) as whatever it was in its Seagate housing, but otherwise perfectly accessible etc. I use it with bot my Mac and windows kit.

You could even transfer it to case with lan port too. The price difference isn't that great, and it would thus give you the choice of usb or ethernet?
