@hong.chen I would recommend seeing if the drivers the manufacturer lists for that item would help. > **[STSW-LINK009 - STMicroelectronics](https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-utilities/stsw-link009.html)** > > STSW-LINK009 - ST-LINK, ST-LINK/V2, ST-LINK/V2-1, STLINK-V3 USB driver signed for Windows7, Windows8, Windows10, STSW-LINK009, STMicroelectronics ---

Hello Hong, I am sorry about the issues you are having. I tried to find the issue. I got the e-mail. Though I think this will be better on the Forum as I have more people to look at it. I am sending an internal request on the Forum for someone to check this. I am sure it is a setting issue if all of them are not working. One of the Engineers will respond on the Forum. ---

Please let me know if the usb 2.0 port and devices can be recognized in Ubuntu Linux or not, that means type lsusb -t is able to display port and device with “communications” class and CDC data ports or not, if not could you please let me know which one can support, I have to replace these 40 units asap. Thanks! Hong. ---

Hi @hong.chen Port A, is (USB-USER), this is the USB port you would use in your application design. There is no ‘fixed’ driver for it, as it’s up to you in the design of your software/etc to also create a matching driver for your application… Port B (USB ST-Link) would use the standard USB drivers from ST to communicate with the on board ST-Link.

Thanks for your response. So I have to flash all of 40 units to be able to show usb ports on windows and Linux? BTW, how to load this hex file into STM32F303Discovery board? Is any detail steps to follow? Thanks Hong ---

> [@hong.chen](#): > > Thanks for your response. So I have to flash all of 40 units to be able to show usb ports on windows and Linux? No, that is incorrect… Port B (labeled USB ST-Link) only needs the ST Drivers… Port A (USB-USER) is for your application to use, by default it’s not used, till your application uses it.
