USB low-full-high speed peripherals Forum Discussions

Hi,

I tried to run the cx3 uvc video project(Cx3UvcOV5640) on windows 10 machine in high speed mode(call CyU3PConnectState() with second parameter CyFalse). The device is recognized by windows and Camera application performs streaming but I  get black screen. The super speed mode is working on same machine and both modes are working on linux machine. What can be a reason for such behavior?

I have another question about linux. We try to run the same projects(high speed and super speed) on windows(8 and 10) under virtualbox on linux.  Should the cx3 work under virtual box? The device in high speed mode is recognized in windows 10 but the capture doesn't work properly - the frame rate is low and i hear the shutter clicks from the device. The super speed device has some problem with descriptors. Here is the output from 'thesycon usb descriptor dumper':

Information for device USB\Vendor_0000_Product_0000:

In documentation it is written that calling CyResetDevice will re-enumeerate.

Under Linux we do not see this behavior: the call returns CY_SUCCESS but the device stays and is accessible via same handles.

Also info about newly enumerated device does not appear in system logs.

Can anyone please elaborate on what exactly the CyResetDevice is for, and the differences (if any) of its effect under linux and windows.

This comes from our task to write a portable software which must function same under different OS.

 Thanks in advance!

Hi.

I took clean example project CCG2 -> power adapter. It didn't initially generate the "Generated_source" -sources to workarea (they also appeared gray in the Workspace explorer) and project complained about missing project.h. Running clean&build generated the missing sources, but now I get error:

Build error: cannot find -lusbpd_gcc (file cm0gcc.ld)

Dunno if it's relevant, but I also get info:

Analog terminal "VBUS_MONITOR.analog_0" on TopDesign is unconnected.

And As said, this is clean import, no changes to code. Just clean & build run. No other projects in the workarea. Attached bundle of the package.

When I build the CyUSB3 driver and updated my device driver I got the following error:
"windows encountered a problem installing the driver software for your device windows 10"

How shall I solve this

hy,i am using a custom FPGA-Board with a CY7. in the other hand, i code a Qt app based on libusb. the problem is: Control Center need windows Driver. but libusb want to uninstall it and replace his Driver(WinUSB v6.1.7600.16385) by zadig. after replacing driver by using zadig app, the windows no longer recognize CY7 and hence control center cannot program it. how can open a usb with libusb without uninstalling it's Driver from windows?or other solution?! thanks

Hi,

Are there any drivers for Cypress KitProg that are needed for USB-device that comes with CYALKIT-E02? Already installed all the software that is available with this kit.

Many thanks in advance

I'm trying to run the GPIF II Designer software. Everytime I start it and either click to create a new project or try to open an existing one the app freezes. I can't do anything with it until I end it in task manager.

I feel like I need to reinstall the sdk, but I can't find any instructions on how to uninstall it from my computer. Any help would be great?
