I have difficulties with an USB repeater cable. It uses an USB hub as repeater.
Here are the error messages:

Every second an error and lsusb needs a long time.
This is the output of "lsusb"

The Genesys Logic devices are the repeater hubs.
The following patch solves the problem:
--- drivers/usb/core/hub.c.orig 2006-05-26 19:40:46.000000000 +0200
+++ drivers/usb/core/hub.c 2006-05-26 20:41:06.000000000 +0200

if (!(portstatus & USB_PORT_STAT_RESET) &&
But I don't know, whether this patch creates other difficulties. Has anybody an
answer?
