- MaxikCZ 2y agoWiat, I recently obtained a thermal camera with USB C that charges only woth USB A -> USB C cable, but not with any C->C cable. Am I understanding correctly that adding a pullup resistor to the camera could solve it?
- sschueller 2y agoThe USB-C spec added cc1 and cc2 which allow a device to tell the host what voltage to provide. Since not all devices need special voltages and an extra IC cost money there is the option to tie both cc1 and cc2 to a 5.1K pulldown resistor each. This tells the host to deliver 5V at max 3A. The maker of your device like many just switched the connector from microUSB to USB-C not reading the spec. So yes, if you add 2 pulldown 5.1k resistors your device should also charge off a USB-C host. That may however not be worth the effort as to how small USB-C connectors pin footprints can be.
- sschueller 2y agoYes. USB A has no cc pins so it will always provide 5V but it may not provide the full 3A which USB-C will.
- hashworks 2y agoYes. I have multiple devices with this issue.
