RPi internal usb hub not working

[sora03]

Hi, I am having problems with my RPi 2B v1.1 the SMSC/lan9512 chip? Internal USB Hub is not working at all, error when booting:

Code: Select all

new high speed usb device number 2 using dwc_otg
indeed it is in host mode hprt0 00001101 
usb 1-1: device descriptor read/64, error -71 
...
another usb device number 3 ...
...
descriptor read error for 3x
...
attemp for power cycle
...
waiting for root device on /dev/sda1...

it is powered by MP1584 5V 3A DC buck converter, prior to this, all GPIO port are broken using the gpio test from wiringPi. the usb micro cable is from the official Pi PSU so no problems with that.
I cannot boot the pi since the root device is on a external HDD.

what is the expected lifetime of an RPi? I've only used mine for 1.5Years

According to your previous posts the GPIO is fried on your Pi, it is possible the USB took a hit as well...

my very first and oldest pi is more about 2 years, its a Raspberry Pi 3 model B bought as a kit set. its the most abused RPi3B that I have. It still runs perfectly fine.

I may (and happy to) conceede the longest time to the veterans in this forum.

Expected lifetime is 20-30 years.

i left it unpowered for a night and the usb smsc9xx is now being detected on boot. lsusb but I cannot power an external hdd which the pi reboots after 2 minutes of uptime

If you have damaged your Pi in the past there may be nothing which will ever make it work reliably.

Try with a another Pi. If that doesn't work then presumably the damage extended beyond the Pi and that HDD may also need replacing.

If the HDD works with the new Pi but not with the old then the old Pi would seem to be damaged beyond use.

Note that connecting something damaged to a Pi may lead to that Pi also being damaged so it might be easier and less costly just to replace everything, start again.

I recently debugged a Pi 3B with apparent broken USB: the system booted fine from the SD card but then the keyboard and network didn't function. The problem turned out to be a version mismatch between kernels, modules and binary blobs in the boot, root and initial RAM filesystem. Everything worked fine after installing a new version of Raspbian on a different SD card.

so what can I do with a Pi that has a broken USB/eth and GPIO pins?

These are what I can think of at the moment.... hope you dont mind...

a. display in decorative frame
b. paper weight
c. electronics/smd parts source

the usb keyboard is working but usb flash drive/wifi adapters do not. i can still watch using kodi.

If anyone is interested in the error messages, I have posted a screen shot of it. at https://z.awsmppl.com:8443/pics/pi2err/index.html

or just see them below:




Conclusion:
1. The Pi 2B was damaged because it was being powered with 5.6 ~ 6V of Input power via microUSB with thick 20AWG cable. So, why did the polyfuse not blow?
2. The Pi's GPIO pins may be damaged because of not using a logic converter in the MCP3002 from a MQ2 Analog gas sensor at 5V

The Pi still boots from an microSD card but the USB and Ethernet are damaged, it won't accept the USB Flash/USB WiFi/USB HDD but it does accept USB Keyboard-why?, HDMI, Audio RCA works. I have not tested the Display connector and Camera connecter since I do not have one. It still works fine as a kodi media center powered by LibreELEC

The polyfuse blows after 6v, so applying 5.5v won't blow it.

You might be able to use the Pi in a headless set up, but being a Pi2b without WiFi and having both USB and ethernet not working, well...

But that temperature, if accurate... Should mean your Pi's SOC will shortly die and is the part you broke when you broke the GPIO bank. It's just taken a while to fully break, but the damage is irreversible.

the temperature sensor of the pi is going haywire, one to five second it is 300+ deg C and another it is 55 deg C. GPIO, ethernet and USB are broken. I am still trying to find ways to use this broken pi, maybe a picture gallery or kodi media center is a good idea.
