usb hub or connection for laptop

i have an acer 7715Z here - works fine; windows 10 on it - but both  USB ports mechanically broken
i am looking for a way to get USB ports in some way, to connect an extermaouse or usb stick
does something like an usb hub exist - that is fed by the LAN port, or SD card reader?
or do you know of other ways to get  an extra usb port ? usb 2 at least, maybe usb 3 ?
1 port is ok, but the more the better, of course !

Bring your notebook to local Acer support agent and replays the broken USB ports. if your PC is still under warranty they will fix it free of charge. our HP agent do that for HP notebooks. perhaps USB ports may soldered to motherboard, then you may have to replays the main board.

Maybe something like this would help?:

This would serve as usb stick. No mouse option.

Otherwise you need to change the motherboard.

It's possible, but I'd be quite surprised.  Over the last several years manufacturers have taken to reinforcing those ports at the PCB and in some cases even use wire instead of PCB traces to avoid this problem.  imo and (I have no doubt in their opinion as well) there's one way that USB ports get broken, and that's by applying too much force when inserting a connector.

In any case this system is now 8 years old and well out of warranty.

Since it's a relatively old system it might have a PCMCIA or Cardbus socket.  You could buy a PCMCIA USB adapter in that case, but it won't be USB 2.

Your cheapest and probably your best bet is to find a friend who is mechanically inclined and ask if he'll take a shot at repairing the connectors.  If he can do it, buy him a case of beer.  Because, if you take the system to a repair shop -- even a locally owned one that only charges $100/hour -- it'll take at least two hours plus parts, and that will cost more than the system is worth.

Second option:  Buy a working used system on fleabay and swap the drive.  Unfortunately I can find no records of any 7715Zs being sold on fleabay for the last six months.  Possibly there are similar models that would support a drive swap; Acer makes all sorts of variations on a single laptop chassis.

Third option:  Thank your old friend for his trustworthy and reliable service, recycle him, and go out and buy a replacement.  Not necessarily new, not necessarily Windows 10, but a replacement.

Hi,

You may need to look something like this https://www.amazon.in/CLASSYTEK-Ethernet-Adaptor-Converter-Connector/dp/B01E0LOJK6?tag=googinhydr18418-21

Most of the people says it's not working, but this one is quite cheaper item, if you could look at similar with quality one then that should do the job for you.

having it repaired is not possible - cost too high
Von Axl - how does that device connect to the mainboard??
>>  to find a friend who is mechanically inclined  <<  that's me

the above does not answer my question
i asked do you know a device that can add usb ports to such a laptop ? obviously not by connecting to USB

Radhakrishnan  that seems to be ok, but i can't find it anywhere here....

Well, you use SD card as a "stick" and then put it into this usb key adapter to transfer it further to a pc that has usb ports working.

If you are mechanically inclined, then open the laptop and see if you can solder the ports if that is the issue. If the ports are broken on outside, then I suppose only a replacement motherboard will help.

After a quick search I found one here:

Oh, that's you, nobus!  You get extra service.

I pulled up the specs on the system and there's no PCMCIA, no Cardbus, no eSATA and no miniPCI.  No available ports at all except for network and the card reader.

Looking at an image of the inside of the bottom of the case, the USB ports are indeed attached directly to the mobo and not as part of the case.  This is confirmed in the 7315/7715 Service Guide, pix on page 75.

The service manual calls out five different motherboards for this system, only three of which have part numbers.

7715 motherboards
I'm gonna stick with my earlier evaluation.  Replace the sockets, replace the motherboard if you can find one that matches, or (horrible hack) clean out the vias on the motherboard for one of the USB sockets, cut the connector off a cheap USB hub, and solder the hub wires directly to the mobo.  Voila, 4 USB ports but you'd have to be exceedingly careful not to catch the dangling hub on anything.

Observation #1:
It does not work fine - both USB ports are broken!

Observation #2:
It wasn't a great laptop to begin with - see review:
http://www.expertreviews.co.uk/laptops/49556/acer-aspire-7715z-review
17.3 in 1,600x900 display, 2.8kg, 2.2GHz Intel Pentium Dual Core T4400, 3.00GB RAM, 250GB disk

Observation #3:
While you can buy USB over Ethernet - https://www.newegg.com/Product/Product.aspx?Item=0ZP-0045-00001&cm_re=USB_over_IP-_-0ZP-0045-00001-_-Product - you can replace the entire laptop and get USB 3 speeds with potentially more RAM and a CPU that is nearly twice as powerful based on CPUBenchmark.net - https://www.cpubenchmark.net/compare.php?cmp[]=779&cmp[]=1122 - for $150 - https://www.ebay.com/itm/HP-EliteBook-8740w-Laptop-Core-i5-2-53GHz-4GB-250GB-Windows-10-Pro/263408551757?hash=item3d545f874d:g:4RkAAOSw8AhaRSbp

observation 1 : splitting hair, tx !
observation 2 : not helpful
observation 3 : that part is what i'm looking for; that laptop does not send it to Belgium -so, not practical
i'm tempting  the replacement of the usb ports, if i can find the right ones (dimensions)
