Do you have any errata information for CYUSB3304?
If you have any errata information, please share it.
Where are the Windows Driver files for HX2?
HX2LP Reference Design Kit User Guide, section 2.4, explains how to load Windows drivers from a disk. Is there an online version of the driver files that can be downloaded?

I use the CYUSB3304-68LTXI HUB USB in a project. I just need the HUB fonction and I don't need the power control modes. You can find the schematic attached at this post.
Note : all the decoupling capacitors isn't represented in this schematic.

Thank you for your feedback !
Can VBUSPOWER be directly connected to VCC (3.3V)?
I want to build in HX2LP inside the Host PC. Therefore, there is no VBUS on the system.
I have one question regarding the crystal placement.
Can someone please check our current crystal placement? Is it advisable to place the load capacitors near to the crystal pins or near to the IC? Kindly review the screenshot for our current placement and advise.
Also as per Infineon checklist, it is recommended to use crystal having drive current of around 600uW but in 4-SMD package we are not able to find the desired part. We are only able to get maximum of 300uW, so we added a series resistor for current limiting. Is it a right way? Also which one is better to use with this IC, Crystal or Oscillator?
Thanks in advance
I'm using CY7C65620 ic for USB hub design. Currently, I'm facing an issue with a driver update. I've tried to use the hx2 blaster software for the driver update, I guess this software has the drivers only for Windows XP and 7. So I need support for the same.
我们的应用需要做下行口USB3.0 和2.0 兼容（上行口是USB 3.0），下行口模块有两种情况：1. USB 3.0 接口模块；2. USB 2.0接口模块，框图如下：
