What is the version of libusb are you using? Please use libusb-1.0.26 or git.

I have a similar smart HUB on Windows 10 x64 and I can not reproduce the issue.

Can u please try getting the handle for the hub. I am using the libusb-1.0.26. libusb_open() is working for the same hub in linux and in windows its fails. I will send you the logs tomorrow morning. Thanks, Janarthanan

The same issue exists. Thanks, Janarthanan

Now this is strange. Let's see if others have the idea how to debug further.

Sep 01 '23 04:09 mcuee

@Janarthanan-S-03

For troubleshooting, can you use Zadig to install WinUSB driver to see if that helps? Thanks. You can also try libusbK driver.

Zadig 2.8 download: https://github.com/pbatard/libwdi/releases/tag/v1.5.0

Sep 01 '23 04:09 mcuee

@mcuee tried using libusb-win32 driver,libusbk driver but the issue still exists.

Sep 01 '23 05:09 Janarthanan-S-03

Hi @mcuee Any update on this issue?

Sep 06 '23 04:09 Janarthanan-S-03

Hi @mcuee Any update on this issue?

Sorry but I have no ideas why this happens. Hopefully others can have better ideas.

In any case, why do you want to talk to this Hub? What is your goal?

Sep 06 '23 05:09 mcuee

In any case, why do you want to talk to this Hub? What is your goal? --> To perform Register Read/Writes.

The issue still exists

Sep 12 '23 09:09 Janarthanan-S-03

Looking at the debug output I cannot tell which driver the device (1.5 is bus 1 address 5, from session 51) is detected as using (or is it just recognized as a hub early in the enumeration?) and I guess the lack of a suitable driver is why it cannot be opened, but I am also not sure what /should/ happen here. @mcuee can you post your debug log from the similar smart hub where it works? @sonatique can you spot from the log what goes wrong? This is one example where I find our debug output is a bit difficult to parse and generally lacking.

Oct 04 '23 22:10 tormodvolden

@tormodvolden Hi, Here is what I can say as of now:

The sentence “unsupported API call for” is generic (I mean: statically defined in a constant string) and will be printed every time a given function pointer is null (her the “open” function pointer is null) (see windows_winusb.h line 96). Therefore this is not an reliable indication that something is wrong specifically with the driver, but only that this function is not supported by the “sub api” we assigned to this device during enumeration
This device was assigned the “USB_API_HUB” api value, because it is a hub. As you can see at line 2475 of file windows_winusb.c, “open” function pointer is NULL in this case. Basically it seems that the Windows backend does not provide any implementation for any function for HUB. In fact, even if “open” was implemented, it would be possible to do anything with the hub device, since all functions are NULL. I have to say that I have no idea why. Linux implementation is simpler and seems to provide “open” and other functions regardless of the type of device

I would say that maybe it would worth experimenting with what would happen if lines 2515 to 2529 would be used to replace lines 2473 to 2487 (i.e. using the same function pointers for a hub than for a regular device). Or maybe should this hub be considered as composite device?

Oct 04 '23 23:10 sonatique

@mcuee can you post your debug log from the similar smart hub where it works?

@tormodvolden The Dell USB Type-C docking station is not with me now but I should be able to test this next Monday.

Oct 05 '23 04:10 mcuee

This device was assigned the “USB_API_HUB” api value, because it is a hub.

I think that should not be correct for this device.

Related to USB Hub under Windows but not the same issue -- for external USB HUB.

https://github.com/libusb/libusb/issues/391

Oct 05 '23 05:10 mcuee

Thanks @sonatique, point 1 was relatively easy and point 2 was close to my guesses, but I couldn't see it explicitly in the log that the USB_API_HUB was assigned (and that it was not reassigned later). If you know the enumeration code well enough it is maybe obvious. But if the WinUSB.sys driver is installed for the device, as per the screenshot, why isn't the winusbx api assigned to it?

Oct 05 '23 07:10 tormodvolden

Do I need to try anything?

Oct 05 '23 16:10 Janarthanan-S-03

@Janarthanan-S-03 Can you compile libusb yourself (from git)? One small thing to get a bit more debug information is to uncomment //#define ENUM_DEBUG in libusb/os/windows_winusb.c

Does the device show up in the Device Manager?

Oct 05 '23 16:10 tormodvolden

@tormodvolden I have complied with the source. What operation do I need to perform?

Does the device show up in the Device Manager? Yes MicrosoftTeams-image

Oct 05 '23 16:10 Janarthanan-S-03

@tormodvolden I have complied with the source. What operation do I need to perform?

You can edit the file libusb/os/windows_winusb.c and on the line where you have: //#define ENUM_DEBUG (around line number 1570 somewhere) remove the two slashes. Then recompile and run xusb -d again.

Does the device show up in the Device Manager? Yes

Yes, that was a stupid question. What I meant to ask was, where in Device Manager does it show up, e.g. under Hub devices ("Universal Serial Bus controllers") or under "Universal Serial Bus devices" as a "WinUsb Device" ?

So it shows up under "Universal Serial Bus devices" but as "USB2906 Smart Hub", thanks.

@mcuee can you post your debug log from the similar smart hub where it works?

@tormodvolden The Dell USB Type-C docking station is not with me now but I should be able to test this next Monday.

This is what I have.

My device is on the external Dell Type C docking station.

What is your device? Is it built-in with the computer or an external device?

Oct 09 '23 05:10 mcuee

@mcuee So yours is under "Universal Serial Bus devices" as a "Hub Controller". What is listed under the Drivers tab? I see that in the enumeration the usbccgp driver is detected and the Composite API is assigned.

Hmm, I think WinUSB API id selected and not usbccgp in my case.
