Good to hear. MikroTik has been improving their documentation, but... it remain very poor at handling where features/abilities that vary by device.
Now...I'm guessing you asked some LLM first, and then came here to forum. While this likely‡ would NOT have helped in this case... but the steering AI towards the new manual.mikrotik.com is likely helpful generally, see ✨ Steering AI to use new manual.mikrotik.com - #9 by Amm0 .
‡ note: I tried testing AI with OP + my RouterOS tools/skills/MCPs... but the LLM "cheated" and found this thread with my answer and OP's response it work... Now Claude did "flag" MY human-made error of using type=miniPCI is type=mini-PCI above in its answer "Note: the forum post showed /system/routerboard/usb set type=miniPCI , but the canonical property value per the CLI reference is mini-PCIe ."
Seems like you figured it out, but just to correct the record:
/system/routerboard/usb set type=mini-PCI
