I've ordered yet another of these dongles. This time, I tried to find a dongle that looks similar to the one sold by Pimoroni and Adafruit. Based on information I found on the Internet, the model number "YS-LAN26" and a unibody plastic shell with a sticker are indicative of this type of dongle PCB. ...

Actually, the new dongle isn't perfect either: It has to be disconnected and reconnected after boot, otherwise it won't be recognised by the Pi0.

I have dropped a post in that thread offering a hub for sacrifice.. Thanks! Fingers crossed @P33M is still willing to help! I have now received my replacement unit that was only marginally more expensive than the failing dongle. From the outside, the only thing that differentiates the new dongle fr...

Cheers your pics prompted me to finally crack the case on one of mine.. and its a match with your failing pics although the crystals seem to be better aligned on mine.. in addition to the badly secured wires from the usb connector the one i cracked also has some loss of insulation scrapped off its ...

News from the Github issue discussion: The problem in fact seems to be with the hub chip on the dongle. Turns out Terminus Technology doesn't produce an SL2.2s chip. In fact, the chip on the dongle appears to be some knock-off from another company, that just mimics the behaviour of the genuine Termi...

They share overlays as DT is a common language describing the hardware. They don't share modules [email protected]:~ $ ls /lib/modules/ 4.14.50+ 4.14.50-v7+ 4.14.50+ is for Armv6 and kernel.img, 4.14.50-v7+ is for Armv7 and kernel7.img. Thank you very much for this information! Don't know how I missed...

Hi, I'm building a custom kernel that I want to use with a Pi 0 and a Pi 3B+. Until now, I've only built the kernel for the Pi 3B+, with the bcm2709_defconfig configuration. The kernel instructions [1] describe separate build processes for building the kernel for the Pi0/1 (bcmrpi_defconfig ; kernel...

In the meantime, I've opened a ticket in the Github issue tracker here:
https://github.com/raspberrypi/linux/issues/2734

So far, it seems like the problem is specific to the Pi talking to a USB 1.1 device via the Terminus Technology SL2.2s USB 2.0 HUB TT0509A18 chip.

Hi, I'm seeing the exact same problem with this kind of ethernet + usb hub dongles! I have started investigating the adapter, tried different OS settings, captured USB communication and cracked open the dongle's case. I have opened a thread about my findings about a week ago: https://www.raspberrypi...

I’ve now scanned the GitHub issue list for relevant entries and found these notable issues: https://github.com/raspberrypi/linux/issues/2692 and https://github.com/raspberrypi/firmware/issues/64 are about usb enumeration failure, but with error code -71. This code seems to indicate hub errors due to...

I somehow found a very interesting thread on this forum [1] that suggested that there is another kernel module called dwc2 that essentially implements the same functionality as the dwc_otg module, sans the Pi-specific modifications (termed FSM - Flying Spaghetti Monster). Luckily, that dwc2 module (...

Thanks for your input! cheers @fd iirc my output from list usb showed nothing for the ethernet h/w only the usb hub. ?mantrox? thats not right but there was an 'M' in it.. Which i confirmed with a pull relist and reinsert and relist.. with the micro usb plug testing with my lappy wasnt an option.. i...

Am following this with interest as i bought 3 x similar devices (usb micro plug) for use with my pi-0's after an evenings googleing i came up with 2-3 driver options to try but nothing definitely stood out as THE solution, and each involved a kernel rebuild and road maps for differing distro's so t...

Thanks for your reply! Given the chipset used in the dongle, you may be seeing a variant of this known, believed to fixed** , old issue: http://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/USBtoLanAdapters.html#Improved_OTG_.22module.22_in_Raspbian_Jessie.2A_solves_dm9601_driver_issues AFAICT, th...

Hi all! This is my first post on this forum :) Introduction I’m a Computer Science student and recently got into Raspberry Pi. It’s been a very exciting journey so far learning about physical computing and the Linux kernel! I’m having trouble getting the Raspberry Pi to recognize a cheap USB hub + e...
