Please share info about power consumption characteristics of your USB adapter

[Janusz Krzysztofik]

Hi,

Please anyone owning one of adapters listed below: if the adapter is supported 
by linux-wireless, please check for MaxPower with lsusb -v and give me the 
result. I am looking for an adapter with MaxPower less than 300mA and would 
rather not buy them all to learn they all do not fit :-).

Once again, sorry for abusing a devel list for this.

Thanks,
Janusz

May want to slap this on the wireless wiki somewhere.

450mA so you can cross this one out from your list.

I do not have any of the specific models you mention, but here are the 3 that I
have:

Netgear WG111v2    [Realtek RTL8187L] USB ID 0846:6a00 MaxPower 500mA
Level One 0301USB  [Realtek RTL8187B] USB ID 0bda:8187 MaxPower 500mA
Dell 1450 USB      [uses p54usb]      USB ID 413c:8104 MaxPower 500mA

There seems to be a pattern!

MaxPower 300mA
but this is the original revision using real rt73usb, I have read that 
never revisions use a different chipset[1].

Hi,

Thanks for all answers so far.

Regarding Luis suggestion: I don't know how to edit wireless wiki, but I 
promiss to collect all information I get from you and post it in a tabular 
form here. Then, you can safely send more answers to my private address if 
you don't want to overload the list too much :-).

Thanks,
Janusz

Just go to:

sign up for an account and edit the stuff into any page. We can help
you organize it.

Mind you, the USB MaxPower is often incorrect. I've had devices that
draw significantly more than what the advertise, and I'm sure there are
devices that draw less...

Luis,

As you have been probably notified, I entered some info into several 
http://wireless.kernel.org/en/users/Drivers/*/devices pages, introducing a new 
column: MaxPower. I hope you accept it.

I will add more if I get more answers (not found any adapter with less then 
300mA yet :( ).

BTW, I'm not sure how to get the MaxPower column dispayed on 
http://wireless.kernel.org/en/users/Devices/USB page. Shall it appear if I 
add that column to every USB driver devices table?

Thanks,
Janusz

Dzięki.

Gdyby podał mi Pan więcej danych: pasujący sterownik, identyfikator USB, to 
wpisałbym to do odpowiedniej tabelki, tak jak zrobiłem z danymi otrzymanymi 
od innych.

Although I think you cannot rely on the numbers in the USB descriptor, FWIW:

  idVendor           0x07d1 D-Link System
  idProduct          0x3c03 DWL-G122 802.11g Adapter [ralink rt73]
  MaxPower              300mA

Sorry, I didn't inted to send that message to the list. I asked for more data 
(driver, USB ID) on Pentagram P 6132-08 to put it into the wiki.

USB IDs:

  idVendor           0x148f Ralink Technology, Corp.      
  idProduct          0x3070                               

and the driver is rt2800usb (or alternatively staging/rt2870sta).

Pozdrawiam.

Hi,

Thank you all who shared their adapter data. All info I got from you should 
now be available in device tables on the linux-wireless wiki.

BTW, I didn't find what I was looking for. Now I'm going to investigate if I 
could switch to using bluetooth networking, that seems less power hungry.

Thanks,
Janusz
