[Q] COM port access on extUSB or elsewhere - P3600 General

Hi
I would like to connect a microcontroller serial UART to my HTC P3600
Found some infos for the G1 extHTC, see at end of post
But I want to have direct access to the COM port (which number ?) under WM6.1 even if I hack the IRDA (it is of no use)
Does anyone have such experience and can share ?
Best regards

serial cable for MDA II How it?

--
You need to create a backup of your original (German) ROM first. For this, you will need a serial cable (no way around this).
Create a connection between your MDA II and your PC by running Hyper Terminal with settings: 115200 baud, 8n1, direct to COM1 port

Nexus 7 with a USB Hub

Hi Guys,
I am using the following setup on my nexus.
> Timur's USB ROM Kernel
> Nexus 7 2012 - WiFi
> USB Y OTG Cable
> 4 port USB hub
> RTL2832u DVB-T Reciever
Basically, if I plug the DVB-T Receiver directly into the Y Cable, it works fine without issue. However, if I plug the 4 port into the Y Cable, and the DVB-T receiver into the hub - the software cannot detect it.
Its a manual switch 4 port hub - so I have turned off all 3 other ports on the hub, so the only one accessible is the one with the DVB-T Receiver, though the software I am running in part (Wavesink) is showing there are errors, which could be either:
RF Device Crashed: Socket Error (-1)
TCP Timeout
Index returned illegal number of samples 0 returned 1024 expected
Any thoughts? is the android only capable of using one usb device at a time directly into the end of the Y Cable?

General Hardware question (USB, 5v, bluethooth)

Hello and Good evening,
I want to make a usb wired mouse into a wireless one. (Provided i cannot solder, and its a high dpi mouse)
Obviously there are two Problems to solve:
- make wireless (bluethooth, i think the only tech that could help)
- make able to power self (short: battery with 5v to usb)
So my question is: is it possible to cut the mouse wire, and connect it with a Y usb cable; in this case it need:
Male this is separated into male power and female data&power to male/female(not important).
The male(*) power get a usb rechargeable battery, the female a bluethooth dongle (**) the Male/female is the other end of the mouse.
* Because the only battery i found is female
** Q: Is there a bluetooth dongle that needs no driver or has build in driver and send usb data+- ?
what i found:
Battery 5v to USB - i01.i.aliimg.com/photo/v1/1935810549/5V_li_ion_battery_pack_3_7v.jpg
Y USB (but wrong order, just for the idea) - ecx.images-amazon.com/images/I/41nWEk7w8SL._SX300_.jpg

connecting 2 coaxial digital audio sources to 1 coaxial input

Hi,the digital audio output in both my Xiaomi Android tv & DVB-S set top box are coaxial. The DAC has only one coaxial input & one optical/toslink input.There is a switch to select either coaxial or optical.The optical input slot now has the blu ray player optical cable connected.
Is there a way to connect both coaxial outputs to this single coaxcial input in DAC ,preferably activating one coaxial spdif coaxial cable (with a 2 way switch) at any one time.
I came up with an idea but uncertain whether it will work.wire up Rca jack socket connectors with a RG 59 or RG 6 coaxial cable & connect a 2 way switch in between the two spdif out signal.The other end connects to an Rca plug.Its just like a Y cable but with a two way switch.
Do you think it is the right way or is it risky? Can the DAC be modified to add a Coaxial input.I don't want to damage the Tv.
If you guys have any other better solution ,please tell me .Thank you.
