usb3 hub not recognised via usb2
My friend has accidentally bought a USB3 hub, which we have not been
able to recognise on anything: On W7-64 Dell desktop, W10-64 laptop, and W7-32 Toshiba laptop, all with USB2 only ports, we get something like "a USB device has malfunctioned" when we connect it. That's plugging it in directly. On the Dell desktop if we plug it in via another (USB2) hub, there is no indication that it has been detected at all. The connection to the W7-32 Toshiba laptop was via a (USB2 I think) hub. On a W10-64 desktop (motherboard something like Sabertooth Z77; it certainly has USB3 ports anyway, and we were definitely using one of them [it has both 2 and 3 ports]), we still got a similar error message; the message included text similar to "request for [something] number failed". (The attempt on the W10-laptop-with-only-USB2-ports might have included that text, too.) I suspect the hub is faulty - do you agree? (A tiny blue light comes on on it when connected or powered.) It has an external power input socket; we've tried fee ding that too, and it made no difference.) My friend is pretty sure it came with no disc; I'd have thought W10-64 on a motherboard with USB3 sockets 2ould have supported USB3 natively anyway. -- J. P. Gilliver.

[] Paul Those (seem to apply to ~2012/3 kit; my friend will have got hers in 2018) look as if the un-updated ones still work, including looking OK in Device Manager, before the upgrade. Ours doesn't. As far as I know, the USB2 section is needed to bootstrap the USB3 section. The initial negotiation uses the USB2 part. If the hardware detects a USB3 section, it can hand off to that once all the details are worked out. If your USB2 won't work, then I would predict the USB3 rates should be unavailable as well. The kinds of failures I would expect: 1) DC power failure, so no VBUS available at the peripheral. Using a device with a LED, might indicate whether power is getting to the downstream side. 2) Individual port failure. Change ports and retest. Of course, you've already tried this. 3) Firmware issue. Firmware erased by Xray machines in customs and excise. At least some firmware-based devices, pass a checksum over the executable image, to detect corruption. If the checksum (CRC) is bad, the devices refuses to perform any function and just sits there. Some devices will have "ROM" and base code present, so they're never really completely dead. The manufacturer can add an external Flash if they want the ability to change the firmware later. Less frequently, a device has nothing but EEPROM onboard (erasable), and could end up completely devoid of CPU functions inside because there is no code. Paul |
