Hi,
We are trying to develope a USB 3.0 compatible mass strorage device using CYUSB3035 FX3S.
We need drivers for windows, linux and mac.
We were expecting at least "CyUsb3.sys" will work however we could not succeed to use this driver
and we suspect it won't be possible. There is a note in the "Cypress CyUsb3 sys Programmers Reference Guide.pdf"
saying that
"...The driver is general-purpose, understanding primitive USB commands, but not implementing higher-level,
USB device-class specific commands. For this reason, the driver is not capable, for instance, of interfacing a
USB mass storage class device to the Windows file system...."
Please clarify. Where can we get CYUSB3035 FX3S USB 3.0 drivers for windows, linux and mac?
Thank you.

Hello Cengiz,
Mass Storage is a standard USB class and hence the device can be used with drivers that are native to the OS. No separate installation of drivers is required.

Thank you Srinath.
Ok but what avoids than Cypress reference FX3SRaid0 project can not enumerate as
a USB 3.0 device in our board? We know other USB sticks work as USB 3.0 devices
in the same PC.

Hello Cengiz,
Using the FX3SRadi0 firmware on our kit, I am able to enumerate the device successfully. Can you please let me know what error do you face on enumeration? Kindly, share the USB traces if possible.
Best regards,

Hi Srinath,
Our board enumerates as a USB 2.0 device successfully but although is
supports USB 3.0,
it does not enumerate as USB 3.0.
I use the same PC with other USB 3.0 compatible mass storage devices
without a problem.
PC ports support USB 3.0 and USB 3.0 drivers are working on it too.
I attach USBTreeView output file. Can you please take your board output
with USBTreeView
and compare with ours?
