[driverloader] DWL - G120 USB with driverloader

[Linuxant support (Jonathan)]

Hi,

we have this entry in our known issues page for DriverLoader at:

http://www.linuxant.com/driverloader/wlan/limitations.php

---
Unfortunately there is no consistent way under 2.4 to prevent the USB 
host controller from automatically re-submitting an interrupt request. 
This issue can cause crashes when initializing a USB device under some 
2.4 kernel and host controller driver combinations. If your system uses 
the "usb-uhci" module, you could try switching to the alternate "uhci" 
driver. If this does not resolve the problem, an experimental workaround 
can be enabled by running "dldrconfig --enable-workaround=usbint". The 
recommended solution is to upgrade to the 2.6 kernel, which is now used 
by default in almost all current Linux distributions.
---

Since you do not experience crashes, it might not be the source of the 
problem. However, it seems that the source of the problem is related to 
the USB subsystem in the kernel:

---
osusb.c: UsbDataCompletionRoutine: error: URB status -110, surprise 
disconnect?
osusb.c: UsbDataCompletionRoutine: error: URB status -84, surprise 
disconnect?
osusb.c: UsbDataCompletionRoutine: error: URB status -84, surprise 
disconnect?
hub.c: already running port 1 disabled by hub (EMI?), re-enabling..
---

Before trying with a 2.6 kernel, you could try with different versions 
of the Windows XP driver and hope that it will fix the problem.
