Re: Rpi4-4GB: USB3 devices not recognized in USB3 port

Okay, RPi4 is up and running with SSD using the StarTech SATA-USB3 cable. Throughput is around 280MB/s, which is approx. 7 times faster than the SDcard. It boots from the SDcard with root on the SSD. I heard there's new firmware coming that supports booting directly from the SSD. Interesting times a...

Re: RPi4-4GB: How easy to blow up the USB chip?

so almost certainly something wrong at your end. Yes, I'm sure.... Just want to know what is wrong... I cannot keep on frying RPi chips :). In the meantime I've got a new RPi4 with functional USB3. I've attached the SSD using the StarTech adapter cable (ASM105x chip) and it seems to work properly, ...

Re: RPi4-4GB: How easy to blow up the USB chip?

One or two pins in the upper row were bent slightly out of place on the ones I was able to repair. Doubled up and crushed beyond recognition on the others. Broke when trying to poke back into place. Other than foreign material on contacts this is one of the only USB malfunctions I've seen. There wa...

All due to physical damage, verified by physical inspection and mostly the delicate USB3 pins. On only one occasion I was able to repair by poking with needlenose.
Can you describe the damage?

The USB3 contacts of the host port are 5 flat, fixed contact 'pads' that look quite robust.

Re: RPi4-4GB: How easy to blow up the USB chip?

It's more likely that whatever connector is being pushed into the slot is somehow damaging the superspeed data pins. That thought also crossed my mind. The system log has a lot of "usb usb2-port1: Cannot enable. Maybe the USB cable is bad?" messages. However I cannot see (strong magnifying glass an...

Re: RPi4-4GB: How easy to blow up the USB chip?

The horror scenario is: insert a USB3 device, works ok. insert another USB3 device, works ok. Insert a third USB3 device - Errors!! And then the RPi no longer does USB3. The earlier working USB3 devices are now only recongized as USB2 devices. This makes me believe that the third device (an SSD atta...

Re: RPi4-4GB: How easy to blow up the USB chip?

Static? I think a USB port should be able to handle that. It is designed to be plugged in whatever. No, my devices are not malicious, they all function properly in other systems. So I can rephrase my question slightly: can a device that functions properly in one or more PCs permanently damage the RP...

I really wonder what is going on. Are those USB3 ports extremely vulnerable? The chip? The contacts?

Re: Rpi4-4GB: USB3 devices not recognized in USB3 port

Nothing peculiar. During the boot/startup de usb hubs are initialized and then the USB3 stick is detected as a highspeed device.
I've added the syslog.
Note that I removed the earlier entried in the log. It starts where I inserted the USB3 stick in port 2. After that I rebooted.

It's good to know the Pi wasn't defective after all. That's one possibility... The other is that this Pi (and the previous one) are defective now .
