Brand new Mac m1 pro doesn't recognize usb devices

Hi it starts charging phones, external hdd but i can't work with data when i connect it with usb. All apple cables are new, and they working with other pc.

I'm checked box in finder to "show external disks". In system information (”usb”) it doesn't appear. In safe mode too.

But sd cards and flash disks are working.

So i have solved this question. In that shop where i bought this Mac i tried to return with 14-day policy but manager told me that we should try on other Mac's they have stored in showcase. And nothing happened. On Mac's with m1 processor (monterey) my external disk doesn't worked, but with Intel (monterey too) it works. We tried different connections and cables and with one of those cables starts this disc. In attachment you can see this "hub" . How he said, it works because this hub have different ports for different tasks. Usb for data, hdmi, and usb-c only for charging so when it connected with USB port in this hub, Mac doesn't think what should he do: charge or data transfer. When i connect it directly as i wrote in my first post of this topic it starts charging and work with data dont available.


But here's a question: why? Intel macs and windows pc can work directly, but M1 Mac doesn't.
