I also tried the CDC Driver Windows Win7 x64 driver from here:
And went thru the installation and still Win7 will not use the CDC Data Interface driver when pointing Update Driver at it...
Well, I got it working on my Toshiba I3 Win7 x64 notebook. Simply using the default PID F232 and pointing the Driver Update dialog to the generated code \ PSOC5 directory worked. The computer recognized and enumerated the COM port and I was able to communicate with it thru a C# program. (I had been using a PID of 0005 before which had been recommended at a Cypress forum.) So I bootloaded as a HID and then switched to a Virtual Serial port. Cool.
So pressing my luck I moved the board to my second older HP I3 Win7 x64 notebook. This time I got an Unknown USB Device. When I tried pointing the Driver Update dialog to the generated code \ PSOC5 directory Windows told me that the best driver was already loaded (gotta love that).
Any ideas? Do I need to change the USB voltage to 5V or something like that? Has anyone seen this before?
Well, talking with myself one more time:
I got both of my computers working with the USBUART by using this code:
/* Start USBFS Operation with 3V operation */
Had seen another reference to using USBUART_1_3V_OPERATION screwing up someone elses Win7 USB serial communication somewhere else in the forum.
SO VOLTAGE DOES MATTER! I think the newer Toshiba was more tolerant to lower voltage USB than the HP...
when nobody talks to you here, Probably nobody made an experience as you did. The "usual" thing is that the windows supplied drivers help. Sometimes it helps to remove the USB-associated drivers and do a re-install. A good and helpfull tool is deview64 which you can download freely from nirsoft.org.
