Kabel USB-A - USB-C ?

"Cables

USB 3.1 cables are considered full-featured USB-C cables. They are
electronically marked cables that contain a chip with an ID function
based on the configuration channel and vendor-defined messages (VDM)
from the USB Power Delivery 2.0 specification. Cable length should be
<=2 m for Gen 1 or <=1 m for Gen 2.[9] Electronic ID chip provides
information about product/vendor, cable connectors, USB signalling
protocol (2.0, Gen 1, Gen 2), passive/active construction, use of
VCONN power, available VBUS current, latency, RX/TX directionality,
SOP controller mode, and hardware/firmware version.[6] "

Ale to chyba nie twoj przypadek.



"USB-C cables
Many cables claiming to support USB-C are actually not compliant to
the standard. Using these cables would have a potential consequence of
damaging devices that they are connected to.[60][61][62] There are
reported cases of laptops being destroyed due to the use of
non-compliant cables.[63]

Power issues[edit]

Some non-compliant cables with a USB-C connector on one end and a
legacy USB-A plug or Micro-B receptacle on the other end incorrectly
terminate the Configuration Channel (CC) with a 10k? pullup to VBUS
instead of the specification mandated 56 k? pullup,[64] causing a
device connected to the cable to incorrectly determine the amount of
power it is permitted to draw from the cable. Cables with this issue
may not work properly with certain products, including Apple and
Google products, and may even damage power sources such as chargers,
hubs, or PC USB ports.[65][66]
