I don’t see nothing related to usb issue from log… may be some gpios are different, but I don’t see conflicts also…
If I receive some additional info from Ugoos I will check it again.
@boot2k3, thanks for the answer! I will wait eagerly 
But do you really think that gpios mismatch can cause such behavior: toothpick boot - USB works, regular boot - USB doesn’t work?
Right now I don’t have any idea. Need to check original dtb/dts first.
Hi,
I have some issues with my ugoos x2 pro Box.
More info is here:
Anyone here tried the H96 Max? Or other S905x2 box that works excellent? I promised a guy a barely know to set up a coreelecbox. He don’t know how to do this, yet. He will order a box, and I will install CE on a SD card, so I am looking for a box with the least amount of hassle possible (easy startup with SD card etc). Thanks in advance.
I recommended the Odroid N2, but he does not want any DIY. He can run the SW though.
Not sure how a s905x2 is less DIY than the N2 with coreelec pre-installed? CE stable - done
CoreELEC 9.2.1 still doesn’t have the USB-OTG (USBv2) port function with Beelink GT1 Mini units. I know why, and It’s an issue that’s easily correctible by CoreELEC team by updating the dtb image. Beelink GT1 Mini & CoreELEC, No USBv2 Port
Are you asking Team CoreELEC to replace the Vendors Bootloader ?
That’s not going to happen.
Ask the vendor.
Or are you asking for a new dtb.img for this hardware ??
Yes. I meant dtb.img for this hardware. Needs to remove OTG mode for that USB-OTG (USBv2) port in order to allow that port to be used more than just a gadget.
Beelink GT1 Mini USB-OTG port which is USBv2 also dual-role device besides, to flash it via PC or hook up USB devices like mouse, keyboard, drives… The dtg is only seeing it as a single-role OTG device with the dr_mode set the way it is currently.
I have just seen this is an issue with some devices like the X2 Cube Thread
Scattered USB issue also HERE
So not so easy fix so far.
You are probably correct, @prynn. But I want to act support as little as possible here. I just want to deliver a suggestion on a box, and deliver a sd-card.
Also, there is a huge amount of delivery costs and import fees connected to the N2 where we live. That can be avoided with other boxes.
Alright, fair enough. If that’s the case I would’ve go with the Shield, if you wanna do as less support as possible.
That is a nice box, in deed. But this kid was all in to Vero 4k+, and I told him not to bother. I have been selling CE on him know and would like to deliver that.
You’ll always get what you pay for. You have the VIM3L with CoreELEC that has a nice price tag and is a wonderful device. Here we tend to prefer SBC’s. In the other devices you have the GT king that is fully supported by CoreELEC. On the cheap end of things people seem to be appreciating the X96 air but like the other devices in that family you can run into a box with a different WiFi/BT chip.
So, you can run CoreELEC perfectly well in a huge variety of devices.
Is 9.2.1 working properly on Mecool KM9 905X2 Box?
Because on Kodi i have small microstuttering on fast moving scenes and want try this if can fix that.
Anyone that works with the dtb images, it should be.
I have giving dmesg logs of USB activity under both Android 9 that has the two functional USB ports, and CoreELEC that only one functional USB port, the USBv3 that’s a host. Available at Beelink GT1 Mini & CoreELEC, No USBv2 Port
USB-OTA (USBv2) port on this GT1 Mini needs to also act as a host too, or do dual-roles and It’s not. From my research, It’s all controlled via dtb image file.
So GT1 Mini users and alike shares such a problem, you can’t use USB-OTG port to install CoreELEC. You have to use another port, and in my case GT1 Mini only has one other USB port and we need to be able to use Keyboard to configure CoreELEC and also operate Kodi. Need to use an USB Hub, also once CoreELEC is installed via USB, the USB-OTG port still remains unusable… Using USB over SD Card does nothing to address the non-functional USB-OTG port under CoreELEC.
