USB C port mounting problem

josephhung

Just hit an interesting issue in the USB C port on Dudu 7, I have a thumb drive that is USB C, if I directly attached to the machine, it can be mounted by android and show in the Files app, but if I wanna the make it easy to access and use a extension cable, the USB thumb seems cannot be mounted. While if I use a USB C hub as show below, the left USB C port cannot mount the thumb drive, other than that port, I can mount the thumb drive on the right side ports.

Is that the problem of android or the problem related to Dudu?

josephhung doesn't it that port for power delivery not storage? Have a similar usb hub and one of the Usb c is a power delivery input to power all usb sockets and possibly charge a connected device.

josephhung Why did you come up with so many reasons but never suspect your extension cord might be the problem?
Plugging it in directly works fine, but using the extension causes issues—it's pretty obvious.

josephhung

Mikescotland Yes… That’s port is power delivery… but didn’t know why an extension cable cannot mount t the drive. It can mount when I plug in iphone with that cable

Mikescotland

josephhung except power delivery input, all of other usb inputs including usbc work. Power delivery isn't guaranteed usually to work flawlessly with storage (depending on quality of the Usb hub of course).

Mikescotland I have an extension cable … If I just use the cable alone with the thumb drive attach to the end. It didn’t recognize my thumb drive, but if I use the same set and insert into my iphone. No issue at all. It is not related to the usb hub at all.

josephhung well then you have an answer, something is wrong with the extension cable. I have hooked my usbc with quality extension (it's in the glove box, ca 40 cm long) and no problem whatsoever.

Note also that the power from the USB-A ports is very limited while the USB-C port delivers much more power (4x or 5x). If you want to connect an unpowered hub, make sure you connect it to the USB-C port on the back side.

surfer63 I'd take it very cautiously with Dudu, they don't specify what's the max amps from the usbc. It might be literally on the max 1A side.. I know, usbc specs, but fyt and Dudu might be a completely different story..

DUDU-Meng it turn out is that the contact of the dudu7 usb c port and the cable is quite poor and wiggle a lot .everytime when i put back the head unit into the tiny space with many wire behind , the port will become loose again. And i think i need to use tape to mount the cable securely to the port.

There are USB-C cables that have srews that fits the screw holes beside the USB-C port

josephhung

JhonnyD Yeah…. I have just purchased this kind of cable… Thanks for helping

The photo shows my previous unit; I have the same harnesses attached in DUDU.

Mikescotland

Astrolux that's great, but I don't see any obvious relevance to this topic?

Mikescotland The USB-C cable is stable in the socket after being connected to this beam.

Hi Guys, anyone try the type C to HDMI converter? Just wondering if I can use this port for rear monitor. I’m currently using the usb A port to RCA, but it’s laggy and low res image quality. Thanks
