best linux for 128 mb ram with USB support
 

i have PIII PC and have 128mb RAM which is the best linux for me which gives me the support for USB also.

hi rajesh, Try with Fedora6. If your system is slow then move to Fedora4. That will be better.

Recommending old and unsupported distributions isn't a good idea, even for older hardware. Fedora 6 is 2 years old, that is ancient in the Linux world, many, many changes that improve usability, stability and security have been made since then.

I would recommend something like Zenwalk, Mepis, Puppy or Xubuntu.

Slackware based distros run on very old machine (P-MMX) quite good. But I will recommend you either to try VectorLinux Lite or Zenwalk. Both are Slackware based distros with LXDE/XFCE and are really fast on older machines, specially with 128M ram.
I personally used VectroLinux Lite on my friend's PI-MMX with 128M ram and we both are very happy with the performance.

try dreamlinux - please say whether it was nice or not.

Dreamlinux is really good. but 3.1 Installer is a bit buggy, neverthless a very nice OS X Clone and overall a good distro :). but I think it will be a bit heavy for him with 128M ... what say?

If it is a good P3 processor, DreamLinux or VectorLinux should manage to run well (with swap ~300 MB). ZenWalk is a good choice too
