USB2 backport from 2.4.27 to 2.4.4/2.4.18/2.4.20

[mchipser]

is there a full current change log???

I am curious if the SMC2208USB is reconized as a USB 2.0 device or still a USB 1.0 device

Thanks

The backport drivers don't magically turn a USB 1.0 device (like your SMC2208) into a USB 2.0 device.

If you're going to use the backport drivers, I recommend this $12 USB 2.0 ethernet adapter.

sorry about that.. for some reason i thought the smc was a usb 2 device.. i purchased a linksys 200m v2 and it works with the new drivers

thanks

I thought I did all my homework to make sure I could do jumbo frames.

HDVR2 & HR10-250
Airlink101 AGIGAUSB adapters

Switch
Switch: Netgear GS605 v2 5 port 10/100/1000 Switch (which claims Jumbo Frame Support (9,000) on the website and on the box)

PC NIC
Intel(R) PRO/1000 GT Desktop Adapter w/ Jumbo Frame support set to 9014 bytes in Device Manager -> Advanced. The choices are

• 16128 bytes
• 4088 bytes
• 9014 bytes
• disabled

When I telnet into my DTiVo and run

ifconfig eth0 down; ifconfig eth0 mtu 9000; ifconfig eth0 up

The command succeeds, and I can run a plain ifconfig to verify the new setting, but if I run the ps command the telnet session locks up.

I've tried setting the mtu using ifconfig as low as 2000, and that also locks up the telnet session with any command that returns more than a screen of data.

Anybody have any ideas?

You might look at the suggestions and tools in this thread. It sounds to me like it is an mtu problem, and, as always, I'm suspicious of the PC side Firewall and VPN software are known to cause problems.

Thanks for the help Jamie.

As it turns out, my problem was in my cables. I hadn't noticed that the status lights on the GS605 switch showed only a 100Mb/s connection to the AGIGAUSB adapters attached to my HR10-250 and HDVR2-1. Apparently jumbo frames don't work at 100Mb/s. Simply switching out those cables resolved my problems.

Newbie question here. I've got a linksys wusb54gc that I would like to try to make work. Apparently its not well supported even under recent 2.6 kernels but I have found a "beta" driver for its rt2570 chipset. What is involved at a high level to backport a particular driver to be compatible with this package?

(And in case I get lazy and just want to watch TV on my Tivo, what's an easy to find adapter with the at76c503 chipset I see in your readme? My wife is holding her tongue about the ethernet cable snaking across the living room and up the entertainment center but that won't last forever...)

BTW, I finally did turn off the TV and haul out the screwdriver and follow the steps to get to where I can telnet to the Tivo and do lsmod. Kudos to Jaimie and this crew for making that possible.

thanks,
chris

It's generally a fair bit of work. A lot of data structures have changed between 2.4 and 2.6, so you are really writing 2.4 code from scratch using the 2.6 driver for general concepts and approaches.

I don't do wireless and don't test the backport drivers with wireless devices, so generally I'm reluctant to suggest anything.

Hey Jamie,

would you consider looking at this adapter and seeing if it can be used??

I have the drivers if needed.. it's a wired cables unlimited brand

thanks!!

What are the usb vendor/product codes? 07a6/8515? It looks it is a pegasus II chip and newer versions of the pegasus linux driver support it. As far as I can tell, all the older pegasus supported adapters where usb1.1, so it might take some overhauling of the code to get decent performance out of a usb2 device.

The first step would be to add the vender/prod codes to pegasus.h to see if it just works. Here's what comes from the linux-2.6 tree:

PEGASUS_DEV( "ADMtek ADM8515 \"Pegasus II\" USB-2.0 Ethernet",
                VENDOR_ADMTEK, 0x8515,
                DEFAULT_GPIO_RESET | PEGASUS_II )

[cyklfreak]

i'm not an expert but this is what is in the ini file

[Manufacturer]
%ADMtek% = ADMtek

[ControlFlags]
ExcludeFromSelect = USB\VID_07A6&PID_8513

[ADMtek]
%ADM851X.DeviceDesc% = ADM8515.Ndi,USB\VID_07A6&PID_8515
%ADM851X.DeviceDesc% = ADM8511.Ndi,USB\VID_07A6&PID_8511
%ADM851X.DeviceDesc% = ADM8511.Ndi,USB\VID_07A6&PID_0986
%ADM851X.DeviceDesc% = ADM8513.Ndi,USB\VID_07A6&PID_8513


i'll try what you said and see


thnks

[cyklfreak]

is there a certain place the pegasus.h file is or is pegasus.o what I am looking for??

sorry but I've looked and am lost!!

thanks

No, it's pegasus.h that you're looking for. You won't find it on your tivo because it's a header file. So get the backport source file and you'll find pegasus.h in there. Jamie pretty much gave you the piece to copy in. Look around, you'll see similar sections. Then you'll have to recompile the 'pegasus.o' from the .c and .h files and copy that into your tivo. If you don't have a clue, I'd suggest you buy a compatible adapter...they're pretty cheap. This level of discussion really doesn't belong in the development thread.

- Add Gen05 (Series3) and TGC01 (SA DT) support for the host modules

- Provide network drivers compatible with 8.x TiVo kernels.

obj/drivers/2.4.20 -- compatible with older kernels (3.1.5, 6.x, 7.x, etc)
obj/drivers/2.4.20-8 -- compatible with 8.x kernels (8.1, 8.1.1)

- Add ADMTEK 8515 Pegasus II USB-2.0 support to the pegasus driver

[Jamie]

2007/10/23 Jamie

Added Gen06 versions of the hosts modules, for the TiVoHD.

2.4.20-8 modules are also compatible with 9.x kernels.
