Part Number: TUSB7340
Tool/software: Linux
We found the TUSB73x0 USB3.0 xHCI Controller Errata (Rev. B) in web, in the work around you have mentioned your driver(TI-provided driver for this device will not attempt to access disabled ports), now we met similar problems in Linux kernel version 4.17.4 and 4.14.0, could you share the driver for Linux to me ? thank you.
Customers should ensure that no access is attempted to the PORTSC or PORTPMSC registers of ports that have been disabled via the PORT(x)_DIS bits. The TI-provided driver for this device will not attempt to access disabled ports, but it is important that custom xHCI drivers and xHCI-aware BIOS implementations also do not attempt to access disabled ports
