rj45 ethernet usb micro adaptor

[peepo]

would either of these adaptors: B00B7CNPAM or B009YYSFAU
connect the Kindle Touch to an ethernet cable** and hence another pc?

ie assuming usbnetworking is installed and working

if not is there something else?

**no wifi, no usb

thanks again

I doubt you could get anything to work without recompiling the kernel to get the device drivers you would need?

[peepo]

thanks Brian, good point, tend to wear too many hats...

reading through: http://www.tldp.org/HOWTO/Ethernet-HOWTO.html

have the feeling that ethercards have been around so long this may be doable...

link to things please.

My gut says No, wihout effort

I suppose you will still need to add USB Host Mode support to Kindle.

Exactly my point.

Much obliged

the simplest possible likely solution might for example be:

modprobe usbnet
FATAL: Module usbnet not found
modprobe dm9601
FATAL: Module dm9601 not found

davicom dm9601 is cheap, popular and in my toolbox...

A few Kindle Fire developers would like ethernet too:

willing to trial if anyone has ideas...

just heard of your efforts to create a USB host port for the Kindle Touch. This is a fantastic thing to do, and your work is much appreciated!

Best thing of all is that there shouldn’t be too much effort needed to create a port for the Touch version. The hardware of the Touch and the K4 is mostly the same(same board, USB chips etc.) and this is also reflected in the code diff, which is minimal and – as far as I can tell – only consists of bug fixes.

The drivers/usb diff of the two kernel trees is also neglegible compared to the USB OTG changes.

Suggested way to port this to the Kindle Touch would be as follows:

1 – Take the K4 kernel as a basis. Copy the the following files/directories from the USB OTG port for the K4 and use these files as a replacement for existing K5 files/directories:
+ drivers/usb
+ arch/arm/plat-mxc/include/mach/arc_otg.h
+ arch/arm/plat-mxc/usb_common.c
+ drivers/power/yoshi_charger.c
+ include/linux/fsl_devices.h

2 – Reapply the USB OTG code changes to the following files:
+ drivers/power/Kconfig
+ drivers/power/Makefile

3 – Now create a OTG defconfig for the Kindle Touch. A working OTG config for the K4 can be found at arch/arm/configs/imx50_tequila_usbotg_defconfig. For the Touch, you will need to create your own.

Use the arch/arm/configs/imx50_yoshi_defconfig as a basis. Then make sure that the following options are set:

+ CONFIG_CHARGER_YOSHI=m
+ CONFIG_USB=m
+ CONFIG_USB_OTG=y
+ CONFIG_USB_EHCI_ARC_OTG=y
+ # CONFIG_USB_OTG_WHITELIST is not set
+ # CONFIG_USB_OTG_BLACKLIST_HUB is not set

The following options should already be set:
+ CONFIG_USB_EHCI_HCD=m
+ CONFIG_USB_EHCI_ARC=y

This is only for minimal USB support. If you want support for peripherial devices such as keyboards, sound cards, USB mass storage etc. you will need to enable additional options.

4 – Additional changes will need to be done to the file drivers/usb/host/ehci-arc.c:

+ To ehci_fsl_drv_deep_suspend and ehci_fsl_drv_deep_resume add the following code to the beginning:

+ if (pdata->operating_mode == FSL_USB2_DR_HOST) {
+ return ehci_fsl_drv_suspend/ehci_fsl_drv_resume(..);
+ }

This ensures that the suspend/resume works also with the internal USB Host port(which is connected to the WAN modem)

Also you will need to UNDO the following code changes done by me on those files:

@@ -78,7 +85,6 @@ wakeup_enable_store(struct device *dev, struct device_attribute *attr,
{
if (strstr(buf, “1″) != NULL) {
wakeup_value = 1;
- wan_set_usb_wake_callback(ehci_hcd_recalc_work);
ehci_hcd_restart_idle();
}
else {

Afterwards, compile the kernel and transfer it to the device. Let’s hope that this works for you. I hope you have got a serial connection to your Kindle because debugging will be difficult otherwise.

Hoper this helps!

Kind regards,

Christian

I really wish I had time to finish this. However time is against me right now.
(I would've done it before now but for the cable, hey ho)

- You will need a *special* USB hub which provides power on the upstream port in order to test the OTG host mode. Alternatively a USB-Y-Cable should do, with the additional power line being connected to your laptop. See here for instructions on how to build such a cable . The cable can also be bought at several computer stores.

Further work still needs to be done such that it becomes possible to connect also normal hubs to the Kindle. Only reason why you need a powered hub is that the Kindle's USB port notices that there is activity on the port and wakes it up from low power suspend mode.

The teamwork here is massive, cant thank you all enough...

not sure whether to pipe down or keep posting, we'll see....

back to set up screen for the moment.

[twobob]

I REALLY wanted to get this done a WHILE ago.

but life gets in the way.

if YOU get it done and share... that would be great
