I was having problems with my usb device, that failed with "hub.c: connect-debounce failed, port N disabled". [...]

Problems seems to be in clearing USB_PORT_STAT_CONNECTION flag after it is being read once. Don't ask me why, but thats what I find out.

What device is this?

This is DIVA MP3 player, but AFAIK this patch "solves" simmilar problem with some card reader.

It sounds horribly broken if it clears STAT_CONNECTION when there is a
device connected.

Yes...

All in all, the patch above is garbage, but the routine is
dubious on two counts and I would like the author to comment.

I don't say it's good solution, but it is the only one I could found with my poor usb and kernel knowledge. And it works. The code that was in kernels before 2.4.19pre2 worked also fine.

I'll see if I have the email in my archives. I forget who originally
wrote this patch.

Me, but here it was first time sent probably by Olaf Hering.
