New Post: My First Week of Librem 5 Convergence

However I’d say there’s a problem in our tps6598x firmware.

Not really. L5 obeys what your hub is telling it, and seems like it tells that it supports up to 500mA over 5V when used with PD source. Some poorly implemented hubs do that, which is why it’s important to check how the hub operates at 5V specifically (dp-alt-mode-adapters.org · master · Librem5 / firmware-tps6598x-nonfree · GitLab). Higher voltages can be enabled in TPS65982 configuration, but that’s not recommended.

If you feel adventurous you can override the input current limit manually:

Yes, you could do that already before as well: sudo i2cset -f -y 3 0x6a 0x00 <VALUE> where <VALUE> is between 0x00 (100mA) and 0x3f (3.25A). See https://www.ti.com/lit/ds/symlink/bq25895.pdf page 32. You can verify the currently set value with cat /sys/class/power_supply/bq25890-charger/input_current_limit This is also useful to set input current limit to a higher value than the default 500mA when using USB-A chargers.
