Dear friends,

OS: Windows 7 (32 bit)

Recently I bought USB TO TTL CONVERTER from eBay.in. Silabs CP2102 IC used in the converter. I have downloaded the VCP (Virtual Com Port) driver and also other Windows driver from Silabs and installed in my PC. I could not able to communicate the uC from PC. When I see on USBDeview, it tells as CP2102 not connected. When I see on UVCView, it tells as "ERROR: no pipes open". There is no VCP created. When I open hyperterminal, it tells as no COM port found. What could be the problem?

images Attached FYR.

Any help?
thank you,
speedEC

open
controlpanel\systemandsecurity\system\devicemanager.

see you have any COM port number included in 'Ports(COM&LPT) section , after you attach your cp2102 device.
 

for some reasons, whether it is by virus or some other problem, I could not able to see the Device Manager. It always shows empty. But, the USB views also do the same.

thank you,
