M\u00f5nikord on soov t\u00f6\u00f6tada USB kaudu \u00fchendatud seadmega, hoides seda laua \u00e4\u00e4res koos s\u00fclearvutiga. Minu seadme puhul on tegemist Hiina lasergrafeeriga 500 mW, mis on \u00fcsna ebameeldiv l\u00e4hedases kontaktis. K\u00f5rvaltoimetena on silmade jaoks otsene oht ning laseri t\u00f6\u00f6 k\u00e4igus eralduvad m\u00fcrgised p\u00f5letustooted, seega peaks seade asuma h\u00e4sti ventileeritud ruumis ning soovitatavalt eraldi inimeste eest. Kuidas aga sellist seadet juhtida? Vastuse sellele k\u00fcsimusele leidsin juhuslikult, vaadates OpenWRT hoidlat, lootes leida v\u00e4\u00e4rikas rakendus vanale D-Link DIR-320 A2 ruuterile. \u00dchenduse loomiseks otsustasin kasutada kokkuv\u00f5tet, mis oli varem kajastatud \u0425\u0430\u0431\u0440-is USB \u00fcle IP tunnel<\/b>, kuid k\u00f5ik selle paigaldamise juhised on ajakohasuse kaotanud, seega kirjutan oma.

\nOpenWRT on operatsioonis\u00fcsteem, mis ei vaja tutvustamist, seega ei hakka ma selle paigaldamisest r\u00e4\u00e4kima. Oma ruuteri jaoks v\u00f5tsin viimase stabiilse OpenWrt 19.07.3 versiooni ja \u00fchendasin selle peamise p\u00e4\u00e4supunktiga Wi-Fi kaudu kliendire\u017eiimis, valides re\u017eiimi lan<\/i>, et tulem\u00fc\u00fcri mitte piinata.<\/p>\n

\nProovime seadme \u00fchendamist Windows 10-ga, kasutades \u00fclaltoodud juhendit openwrt.org-ist. \u00dctleme kohe: katse on m\u00e4\u00e4ratud eba\u00f5nnestuma. Esiteks, k\u00e4sitletakse ainult Windows 7 x64. Teiseks, on antud link thread'ile sourceforge.net-is, kus pakutakse alla laadida Dropboxist 2014. aastal patchitud draiverit. Kui proovime seda Windows 10 all k\u00e4ivitada ja meie seadmele \u00fchendada, saame vea:<\/p>\n

\nSee on seotud sellega, et klient ei t\u00f6\u00f6ta serveriga, mis on kokku pandud kerneliga, mis on vanem kui versioon 3.14.

Nii et esmalt palutakse installida sertifikaat, ja seda kahel korral. Okei, paigutame selle Trusted Root Certification Authority ja Trusted Publishers.<\/p>\n
Edasi tuleb operatsioonis\u00fcsteem viia testre\u017eiimi. Seda tehakse k\u00e4suga<\/p>\n

P\u00e4rast seda k\u00e4ivitame Windowsi ja teeme bcdedit.exe \/set TESTSIGNING ON<\/i>
\nWindows \u00fctleb, et k\u00f5ik on korras. Taas k\u00e4ivitame ja n\u00e4eme paremas alumises nurgas tekstiga Test Mode, versiooni ja OS-i build'i numbrit. <\/p>\n
Milleks on k\u00f5igi nende man\u00f6\u00f6verduste eesm\u00e4rk? Allekandmata draiveri paigaldamiseks USB\/IP VHCI<\/b>. Seda tehakse, laadides alla failid usbip.exe, usbip_vhci.sys, usbip_vhci.inf, usbip_vhci.cer, usbip_vhci.cat ja k\u00e4ivitades need administraatori \u00f5igustega<\/p>\n

Hiina graveerijaga tuli veidi vaeva n\u00e4ha, kuna katse paigaldada selle draiver CH341SER koos graveerijaga kaasasoleva installeriga (jah, graveerija on Arduinoga), USB\/IP VHCI kukutas Windowsi BSOD-ile. Kuid draiveri CH341SER kuni<\/b> \u00fchendamine seadme kaudu usbip.exe lahendas probleemi.<\/p>\n
Kokkuv\u00f5te: graveerija m\u00fcriseb ja suitsutab k\u00f6\u00f6gis avatava akna ja suletud ukse juures, mina j\u00e4lgin p\u00f5letamisprotsessi teisest toas oma lemmikprogrammi kaudu, mis ei kahtlusta midagi.<\/p>\n
