I have found into the forum that there are different versions of the broadcom chip (bcm4333 or bcm4702) according to the wl500g release.

So if someone have a wl500g with a bcm4333 inside can you confirm me, or infirm me, that some wl500g already have a working usb 2.0 host.

bcm4333 chip is not a 'router' chip but a client chip, it is a wrong labeled bcm4702 chipset

probably some fraud business

Hello all

I would like to thank the forum members for the usefull information I found here.

I now have in front of me two Asus WL-500g wireless routers. One of them was made in Taiwan and the other two in China. All of them have "Version 2.40" printed on the PCB and are virtually identical, except for one IC. The one from Taiwan has a Broadcom BCM4333KPB in place of the BCM4702KPB found in those from China.

Broadcom states the following:

"AirForce BCM94333 combines 54g™ wireless LAN technology with the high-bandwidth USB 2.0 interface, which allows equipment vendors to provide a simple upgrade path to 54 Mbps for home and enterprise computing systems. The USB interface gives users the ability to easily add standards-compliant 802.11g and 802.11a/g to desktop systems without removing the PC chassis cover. USB 2.0 technology delivers 480 Mbps of bandwidth, which is necessary to support 54Mbps wireless connections, while legacy USB 1.1 systems are capable of only 12Mbps."

I connected a USB 2.0 hard disk to the USB port and made tranfers of some large files. The throughput was less than 1 MB/s, which obviously corresponds to USB 1.1 performance.

Nevertheless, this raises the question: if software support is added to the 500g's firmware , will it be capable of USB 2.0 performance?

Thank you and regards
Miguel Medalha

This is a "You wish" situation.

Just like Antiloop says: Its probably a mislabled chip otherwise the WL-500g wouldn't work.

How can you add software support so the hardware supports Usb 2.0?

Oleg stated in the previous thread about this that the 500g does not support usb 2.0.

So never mind what software you try to run on it, it will never support it because of hardware limitations.

If you want usb 2.0 you have to get a deluxe version.

I suppose you didn't read my post...

Broadcom states that the BCM4333 IS a USB 2.0 chip.

""AirForce BCM94333 combines 54g™ wireless LAN technology with the high-bandwidth USB 2.0 interface (...)"

Some 500g's come with a BCM4333 instead of a BCM4702. What I was asking was the following: If we include EHCI support in firmware, would we have USB 2.0 on those routers that come with the BCM4333?

Thank you!

OK, looks like you are missing something.

BCM4333 is Bridge Processor, so it may contain even Hi-End DVD receiver onboard, but it can not run MIPS32 program which is actually 500g firmware :)
BCM4702 is Network processor which is actually MIPS32 CPU + some networking stuff.

So you of course can enable EHCI, UHCI or AX.25 but the question is - how are you going to use it without CPU????

Again. There is a chip with wrong lable.
