Raspberry Pi 3B+ can not boot from a USB SD card reader

Preamble

A Raspberry Pi 3B+ (not the 3B) can boot from an external USB drive or stick “out of the box”. However, It can not boot from an external USB SD card reader… why is that?

Uni USB 3.0 Ethernet adapter on Pi 4

Preamble

This USB to Ethernet adapter was required for my cluster (How to build a Raspberry Pi cluster). The Pi has drivers that recognise the adapter, however it doesn’t quite work out-of-the-box.

Raspberry Pi 4 – SD to SSD

Preamble

Using a WD Blue 240 GB, and this JMicron based unbranded clone USB 3.0 to SATA adapter (capable of UASP),

I tried to get either my RPi4 or Pi 400 to boot from an SSD instead of the SD card.

However, this particular USB/SATA adapter does not support booting via the USB 3.0 port on the Raspberry Pi…

Aukey CB-H19

Preamble

I bought this on eBay, Aukey USB 3.0 (7 port hub) Mains Powered 3 Charging Ports 2.4amps, £9.16+2.97

I purchased this to use in conjunction with the Nanotech dual USB 3.0 express card, which was struggling to provide the current for a 5TB Backup Plus USB drive, with the associated over heating issues. I hoped that the external PSU would alleviate the power draw and over heating issues experienced with the NanoTech ExpressCard. See ExpressCards on Santa Rosa MacBook Pro for more details about the overheating issue.

Orico H4013-U3

Preamble

I bought this 4 port USB 3.0 hub in Fortune for 590 baht (from Orico Thailand it was 690 baht). It is a plastic hub, no screws, no way of opening it up to see what is inside.

Reducing USB port usage (on Jetson Nano)

Preamble

Following on from Jetson Nano – basic specs, here are some options to reduce the USB port usage to just one port for keyboard and mouse… this obviously could apply to any computer with limited USB ports, not just a Jetson product.

GPG Hub Pro

Preamble

Nice looking 10 port USB 2.0 hub, for 10 baht.

Dead or dying USB sticks

Preamble

Links to trying to fix a dead or dying USB stick… but let’s face reality and just throw it away, mourn the lost of data, and move on…

Logitech receiver found

Preamble

No casing, just the USB. Been run over by a number of cars. USB connector pretty flattened out. Seems to work. However, as a Logitech receiver it is enormous!!! Maybe BlueTooth or something?
