Hi
I am using cypress cy7c68013a-100a and driver cyusb.sys in "Cypress Suite USB 3.4.6"
for win 7 in wlh folder.
and change .inf file (my .inf is attached)

View attachment cyusb.rarView attachment cyusb.rar

and build a board according AN15456 in this address


**broken link removed**


When I connect on some PC's running Windows 7, i see "the device is not recognized" and "this device connot start(code10)"!


I checked my hardware again and again.but i see this error yet


* i can't find 'tps3820-33' for reset pin so i use a 100k from reset pin to 3.3v and a 0.1uf to gnd *

'tps3820-33' is my problem?!!


Thanks in advance for any help you can offer

any body can help me

Your problem could be the 100KΩ resistor you are using as a pullup on the RESET pin. Try dropping it down to 10KΩ and swap out the 0.1µF cap for a 1µF cap.

The device maybe stuck in reset state.

Below is a schematic for a custom development board which may give you some pointers. I would also advise you to post your schematic, there maybe other issues as well.
