USB Host

---

anyone has tried yet usb host functionality ? I found the drivers of ETEN M600/G500 but not tried yet... processor should be the same so the trinity should support this function.

Thank you for your enquiry, the p3600 was not designed to allow usb memory expansion as such there is no current or planned method to enable what you have requested.

It may be possible to find a 3rd party solution but this would not be supported by ourselves but the solution supplier.

Should you have any other problem, please do not hesitate to call us. Your Local number can be found at http://www.europe.htc.com/support/cs_by_phone.html

Best regards,
HTC Support

Could you share either a link or the file?

Should be this

OK, I'm with Hermes, but anyway... According to the specs, E-Tens have S3C2440 while we have SC32442, but they should be the same. The schematics of the evaluation board (p.6) shows that there are two USB hosts: one from DN0/DP0 pins, the second from DN1/DP1 pins. The latter can also be configured as USB Device... and that's what we have at our MiniUSB connector.

So... if E-Ten uses the first USB Host pins, we're out of luck. If they've implemented it in shared mode, the driver should work. But I have a reason for a doubt: M600/M500 have separate I/O pins for USB host and device, while the connector itself is provided on the cradle. If they made it shared, it would be more easy to implement host/device sharing in the cradle rather than in the device...

A soldering iron may help, but I don't want to loose the warranty yet.

An owner of the Platform Builder may recompile the driver to utilize the shared pins as well. That's a better solution.

If you want to make an adapter for tests, note, that you need to supply +5V from an external power supply (which can be a PC USB port), and that you don't need to cross the pins: DN1 is D- for both host and device, and DP1 is D+ for both. Nothing but connectors and wires should be required.

One more note: a USB Host driver for a shared connector should shut down USB Device driver, something similar that WM5torage does. This also makes me doubt that E-Ten uses shared pins, and that's why I believe that a different driver is required.

But it should be possible!

OK, I've made an adaptor from MiniUSB male (to TyTN), USB A female (for devices), and MiniUSB female for power supply.

In the MiniUSB male I shorted pins 4 and 5. At least this way I can use it for charging from other power supplies, and I think it hould not harm, because pin 4 on GND means USB Host for MiniUSB.

I've installed the above drivers, and also USB Mass Storage drivers (attached).

I have a USB mouse, a card rider (4 slots), an MP3 player, and an RS232 port.

Nothing but MP3 player showed any sign of an activity in all my tests.

The MP3 player shows "MASS CONNECT" on its screen if it detects USB activity. If it does not, it just turns to normal operations, showing that it takes power from USB. It turned to this mode after I installed the attached driver. But I see no a mounted disk on TyTN itself.

So, it works somehow, and I'm almost confident it can be made to work...

Probably I just did something wrong... Who else wants to try?

I must add that installed stuff didn't affect the USB Device from working: ActiveSync connects OK, and WM5torage 1.73 works as before.

Hardwarewise, there are a couple of things to try: disconnect pin 4 from GND at the phone side, disconnect power supply from the phone (providing it only to the attached device), or both...

i'm waiting connectors to try something by myself too. Thanks Lurker0 for all this tips.

thread about usb host from eten users

I ended up with a hard reset Of course I made full backup before the tests.

I've found out that GPRS stopped working. The error messages were like "Modem not found" and "The current call should be finished before data connection" (from memory and ranslated from Russian).

Then I found out that hardware settings for OHCI are wrong:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\OHCI]
"MemBase"=dword:B0900000
"Irq"=dword:0000000B
"UseExistingSettings"=dword:00000000
"MemLen"=dword:00001000
"SysIntr"=dword:00000011
"Order"=dword:00000001
"Index"=dword:00000001
"Dll"="ohci.dll"
"Prefix"="HCD"
"InterfaceType"=dword:00000000

IRQ should be 0x1A (from working registry and also Samsung datasheet), and memory base 0xB5900000.

I've deleted ohci.dll and usbd.dll, then uninstalled that HID driver to no available. I needed a working phone now, and decided to hard reset and restore.

It's strange why IRQ and MemBase were wrong. It may explain why it didn't work. Good I noticed them before tests.
