USB Mini to (the other) USB Mini (?)

---

I have a a USB mini extension lead, so I'm trying to plug in a 3-to-1 adapter to it. So male USB mini, the a-symetrical type (flat one side) to a female USB mini, the symetrical type (wings on both sides). Obviously this doesn't fit!

So is there a USB Mini (female a-symetrical) to USB mini (male symetrical) adapter?

Or could someone at least tell me their proper names so I can google it?

What are you trying to achieve? If it is to increase the cable length between the 3in1 and the Kaiser, I think you would need an ExtUSB patch lead with all 11 pins wired to retain the functionality of the 3in1. I don't know if these leads even exist.
The Asymetrical female socket, like the one on the base of the Kaiser, is double sided on the internal plastic "island" and has 5 contacts on one side and 6 contacts on the other.
The power and data are on the top 5 connectors.
The audio in/out & talk/end are on the bottom 6 connectors.
This is known as ExtUSB and is peculiar to HTC devices.
The Symetrical plug/socket is standard mini USB and will only ever have power and data connections. The mini USB plug only connects to the top 5 connectors in an ExtUSB socket.

Ouch, my dreams of the perfect in-car system dashed! Thanks wizzard that's really explained it very well.

The objective is to have a nice looking car install with only one wire leading to the Kaiser, and the 3-in-one hidden. So ideally:

Power \/
Audio > 3-in-one >> USB extension >> Kaiser
Hands free /\

It was hard enough finding the mini USB extension, so as you say an ExtUSB extension lead may not even exist

I purchased this adaptor for less than £10 from ebay. It ticks all the boxes for me and is the most discrete adaptor I could find. The 3in1 adaptors like this one dont come with a mic so wont work as a hands free without additional adaptors.
My intention is to have the plug fixed to a Brodit mount. The cable is no thicker than headphone cable. This 90cm cable will route to behind the steering wheel on the cowling. The adaptor is flat and low profile with the answer/hang up button on the top. Easily pressed through the steering wheel spokes. The audio 3.5mm and mini USB leads plug in at right angles to each other but will easily route out of site, behind the dash to USB car charger and 3.5mm MP3 In socket on the head unit.
It all works as expected, and even at Motorway speeds callers can hear me clearly. Voice Command works fine, TomTom and Media Player sound great. My only problem is alternator whine when charging, which I think is just an earthing problem. When I get it all properly finished I will post some photos.
After work, wife, kids etc. have finished with me.

Thanks Wizzard. Not a bad solution, and the best so far without the existence of an ExtUSB extension lead.

My only problem with it is that (I assume) it forces the kaiser into handfree mode even when all I was to do is charge and listen to music from the 3.5mm connection.

Again, I am assuming here, but I thought the second adapter you cite would only initiate hands free when I plug in the hands free into its port. I could be wrong on that one though.

Perhaps my issue is a small price to pay for 8gbs of music in the car

I dont have the bulky 3in1 to test, sorry. For me when listening to music and TomTom the audio mutes when I take a call and then resumes seamlessly on hang up without needing to physically touch the Kaiser. I only need to touch the Kaiser to press the Voice Command key once to launch programs and initiate calls.

Hi!


Unfortunately the link to the item you have is broken...

I'm trying exactly what you wanna do, I bought this extension.
Is this the same of you?

It works, but I have annoying noise on audio when it's connected to the USB power jacket.

How to fix this?


Thanks a lot.
