problem in XP for USB

[chacha1234]

I ve been using jetflash v.30, 1GB (transcend). Its been working fine ;

But last week i installed driver magician and updated drivers as recommeded by it;

and after this whenever i plug in my jetflash (onto the same port as i used to) it shows a NOTICE its could work faster than ....if connected to usb port 2. And now file transfer from or to the flash drive is very slow (but previously it worked very nice on the same usb port)

So my port is USB 2 and jetflash is also so (latest v.30).

pls suggest me what to do so that my flash drive works faster as before.

NB: I ve uninstalled driver magician;
