USB 3.0 XHCI Windows 7 Driver Problem

Hi Jonathan,

What you are experiencing is weird. Actually in several application we have developed we use the same IOCTL you mentioned with no issues at all. What version of the TI's xHCI driver are you using? Are you using the latest available? Make sure to use the latest driver available at ti.com.

Also, which usbview example are you using? Usbview has suffer lots of changes specially to handle USB3.0 devices, maybe you are using an older example and that is why it is crashing. I have used USBView with the TUSB7340 and TI's driver and everything works well.

Could you provide more information about your particular application?

Best Regards,

Alexis Cortes.

Hi Alexis, I have tried several versions, including specifically 1.12.25.0 and 1.16.3.0. It's difficult for me to tell which version of USBView I'm using - one, marked 2.0.1 doesn't work, but I found a newer 6.1.7 that works correctly.

The particular application is a tool that performs raw communication with USB printers. While the Microsoft USB Print subsystem is used to handle the printing operation (without use of windows printer drivers), some advanced queries are done as part of the diagnostic data.

When a printer is connected to the port on the TI controller, these queries succeed but populate memory with invalid data. Here are some examples. On the TI controller, these calls do not generate traffic, but succeed. 

An HP Printer on USB 2.0 Port (Intel):
Enumeration Successful - 1 printers found.
Successfully connected to Handle 1
USB Standard: 1.10
Control Endpoint Size: 8
Vendor ID: 0x3F0
Product ID: 0x517
Device Version: 1.20
Manufacturer Name: Hewlett-Packard
Product Name: hp LaserJet 1000
This function is not supported on this system. (From InternalGetStringDescriptor) This printer does not support the requested string descriptor.

The same printer connected to the Ti Controller:
Enumeration Successful - 1 printers found.
Successfully connected to Handle 1
USB Standard: 165.165
Control Endpoint Size: 45
Vendor ID: 0x6150
Product ID: 0x6B63
Device Version: 72.61
A device attached to the system is not functioning. (From InternalGetRawStringDescriptor) DeviceIoControl failed to retrieve the string descriptor.

A Zebra Printer on USB 2.0 Port (Intel):
Enumeration Successful - 1 printers found.

USB Standard: 2.0

Same printer on TI Controller:

USB Standard: 165.165

Here is a snippet of the code driving the queries, in this case the Product ID.

The enumeration code is the only thing I've omitted here, because it is quite long. I am happy to post it if it would be helpful. It basically enumerates the USB Printers with SetupDiEnumDeviceInterfaces, then calls SetupDiGetDeviceRegistryPropertyA with SPDRP_ADDRESS to get the hub address, then calls CM_Get_Parent, CM_Get_Device_ID, SetupDiOpenDeviceInfoA and SetupDiEnumDeviceInterfaces to create a structure that can be used with  SetupDiGetDeviceInterfaceDetail to get the path to the stack that is handling the hub that the printer is connected to, against which the queries are issued. I can also provide complete code\compiled examples if that would be useful.
