connecting to startkit problem

Postby MarkBot » Sun Mar 30, 2014 7:39 pm

so i got my startkit the other day and i have been having some issues with the built in usb-jtag connection.
when i connect my startkit over usb it will find the driver and install under libUSB-win32 Devices but i cannot connect in the composer or see a device in the terminal window using xrun -l, however!!! if i uninstall and remove the drivers in device manager then refresh and brouse to the xmos folder C:\Program Files (x86)\XMOS\xTIMEcomposer\Community_13.0.2\drivers\xmos
it will install and then i can see the device, but as soon as i run code or flash the device disconnects and i have to uninstall and re install the drivers to see the connection again.
i have searched Google and this forum and cannot seem to find a solution, but i do see people having the same issue, also i have tried the known working win7 drivers as stated in other posts and they work the same but disconnect.

i have other versions of lib-usb installed for running avrdude with various programmers and have tried uninstalling all of these in case they were conflicting to no avail.

im running windows 7 64x
the lib usb driver is 11/19/2013 version 0.1.12.1

any suggestions or pointers would be greatly appreciated.
