Hello,
I am using the TUSB3410 in a design where it is operating as a generic RS232 port.
There is no attached external eeprom and there is only one device present in the system.
The latest driver (downloaded as[swrc094g].zip is installed in Windows 7 Professional and 7 Embedded as COM11.
We always get an error with the very first time when we open the port in Windows.
For example, if we use WinSSD from SeaCOM, we get Access Denied. If we close the port and re-open it, it works fine.
If we use BurninTest Pro 7 and select COM11, we get COM Port not ready. If we close the port and re-open it, it works fine.
It is always the first access to the device where we seen an error with com port access.
Has anyone else seen this before?
