Hi All

This is a bit OT, but here it goes: After a power-up of the Pc, there is no light in the USB-dongle, and when starting Proton I got the Error-message "USB Key not found!". If I then pull out the dongle and insert it again, the light comes on plus a ding-dong sound from the Pc, and then the compiler runs without any problems.
How do I cure this little problem, so the USB-dongle is powered up, at the same time as the Pc ? :confused:

Hi Jens
What system are you using.
I have had this type of problem when using USB devices.
It seems to occur on W98 W98SE systems.
WME and above work ok on startup.
I haven't upgraded to the developement suite yet so don't have a dongle.

If youre running w98 then i think it may be an operating system problem rather than the dongle.

Hi Alan.
My system is XP pro (servicepack 2). I'm pretty sure too, that the problem has something to do with the operating system, but how do I fix it ?

I have the same problem for usb devices on XP, no idea how to solve it though.
Maybe there is a program or task that you could set up that would re-initialise a search for usb devices on startup?

The FAQ section is rather small but it's growing. The following might be of help:

No, it did not cure the problem. Also I followed the PDS installation describtion very carefully, and did not insert the dongle before installation of PDS.

This is a problem with certain USB chipsets and not the USBkey. As you state a simple unplug and plug back in will usually cure the problem, I know there are a few chipsets with this problem and as far as i`m aware there is no driver fix as of yet. Try to use the USB drivers supplied with the motherboard (or the specific drivers for that chipset) and not the Generic USB driver supplied with WinXP as although all usb devices are supposed to conform to this standard , some don`t.

The motherboard have the Intel 82801DB chipset. According to Intel's driver site http://support.intel.com/support/chipsets/sb/CS-009262.htm the USB-drivers are provided in service pack 1 for Windows XP.
